9. What are the specifics of the microwave modules developed by the enterprise?

The main products of the enterprise are broadband powerful and low noise amplifiers of the microwave range.

The advantages of these devices:

•  wide band of frequencies (from octave to decade);

•  dense packaging, low weight and dimensions (avionics);

•  combination of continuous and pulsed operating modes, rapid transistor power modulation option;

•  application in active multi-beam antenna systems (normalized phase-frequency characteristics);

•  operation in wide (from minus 40 ... 65 to plus 60 ... 85 degrees) temperature range, built-in compensation circuits for gain temperature changes;

•  operation in severe conditions;

•  optional additional service functions (built-in stabilizers and power converters, output power detectors, digital transmission ratio control, telemetry, etc.)

•  The company also develops and manufactures electronic components based on amplifiers of own design, transceiver modules for phased array antenna based systems, and other microwave modules of varied functionality.

 

10. What component base is used in development and production?

The products are developed and manufactured utilizing mainly imported component base, primarily microwave transistors and monolithic integrated circuits (MIS). The use of imported active elements allows the development of the products of potent technical parameters and reliability.

 

11. Is it possible to use domestic component base?

In case of performance of mandatory R&D for the customer’s account and availability of domestic component base of satisfactory required quality, the use of domestic component base is possible.

 

12. Do you anticipate to widen the use of the domestic microwave component base?

The company is interested in the emergence of modern domestic transistors and monolithic integral circuits of microwave range and cooperates with Russian enterprises (JSC "RPC "Istok", NPF Mikran, JSC, JSC Svetlana-Rost and others) in this field.

Given a choice of components, our enterprise is guided not by the of origin of the manufacturer, but by the components’ technical parameters, reliability, stability of parameters, price, delivery time and other objective characteristics.

 

13.       How are the products tested before shipment to the customer?

The pre-shipment procedure of testing of 100% of microwave modules is as follows:

• continuous 96-hour thermoelectric operation test of module casing temperature of +95 degrees Celsius;

• thermal cycling (7 thermal cycles);

• single impact test.

 

14. Is it possible to develop and manufacture functionally different (other than broadband amplifiers) solid-state modules, for example, modulators, phase shifters, attenuators, pulse amplifiers?

Yes, it is possible. The qualification of engineers and developers of the enterprise allows to create complex multifunctional microwave modules that include mentioned devices, as well as transceiver modules for phased array antenna based systems.

 

15. Is it possible to develop modulators and power supplies for vacuum microwave electronics, for example, traveling wave tube?

No, it is impossible: the profile field of our enterprise is solid-state electronics. The company at this time does not have the infrastructure and specialists required for the development of modulators and power supplies for vacuum microwave electronics either at present, and has no plans of such projects in the future.

 

16. Is it possible to arrange supply of 1 pc of solid-state module?

The company supplies most of the modules in quantities of 1 pc. The ordered quantity and the price of the contract does not affect the priority of delivery - for the company all orders are equally important.

 

17. Is it possible to order a module from the product catalog with alterations done in accordance with the customer’s requirements?

Alterations may be different in every case: everything depends on the scale of required modifications to the product. For example, at the request of the customer, we can supply a module with connectors of an inch thread instead of a metric one, this does not affect the price, but may affect the delivery time.

Serious alterations require time and money. Therefore, it is optimal for the customer to apply and pay for the implementation of design and development related to required alterations to the end product with the required amount of checks and tests. In this case there is a high probability of receiving high quality product. Our company does not practice making changes "on the fly", in the process of fulfilling of the supply contract. However, there is the option of development of modifications to manufactured devices at the expense of our enterprise, in case of conclusion of supply contract for significant quantity of devices that covers the expenses for such a development.

 

18. Is it possible to use a microwave module in a wider band than specified in the passport data (advertising catalog, technical specifications) for it?

In some cases, it is possible. Enterprise engineers can measure the parameters of amplifier’s operation out of passport frequency range and inform the customer accordingly. In any case it is up to the customer to take decision to use the amplifier in the extended frequency band.

 

19. Is it possible to use a broadband amplifier (from the enterprise catalog) for amplification in a narrow band or at a fixed frequency?

It is possible. However, in our opinion it is not the optimal use of the amplifier, since broadband amplifiers of a certain power are as a rule noticeably more expensive than narrow band ones. In addition, a number of parameters of a broadband amplifier (for example, efficiency, harmonics, etc.) may be worse than analogous parameters of a narrow band amplifier.

 

20. What is the process of warranty repairs of products?

20.1. A malfunctioning device is sent to the company by the buyer together with the passport with pre-filled out “CLAIM INFORMATION” section.

20.2. The company's specialists analyze the malfunction (at the request of the buyer - cooperatively with the buyer’s representative) and issue the inspection report.

• In case a failure is caused by internal defects (failure of a component, defective assembly or design), repairs within the warranty period are free of charge.

• If there is evidence of improper handling of the product (external breakdowns and mechanical damage, mass failure of many components, burnout of external circuits, signs of overheating, etc.), the claim is rejected, and the device may be repaired for the buyer’s cost or returned to the buyer.

20.3. The repair period usually does not exceed 1-1.5 months, depending on the amount of work.

20.4. Warranty and post-warranty repairs are carried out AT THE ENTERPRISE’S PREMISES, for special measuring equipment (vector and scalar analyzers, PC-based workstations with special software) are required in order to identify and repair damage, measure and confirm the conformity of the electrical characteristics with the documentation. All the required equipment is available to the engineers of the enterprise.

 

21. How are post-warranty product repairs carried out?

The company has the same serious attitude to the warranty and post-warranty repairs, therefore, at the request of the consumer, post-warranty repairs are carried out on a compulsory basis. The procedure for applying for post-warranty repairs is as follows:

21.1. A malfunctioning device is sent to the company by the buyer together with the passport with pre-filled out “CLAIM INFORMATION” section.

21.2. The company's specialists analyze the malfunction.

21.3. Depending on the severity of the damage, the buyer is billed for repairs.

21.4. The repair period usually does not exceed 1-1.5 months, depending on the amount of work.

 

22. What is the "normalized phase-frequency characteristics" of the microwave module?

Some types of amplifiers, intended for use in active multipath antenna arrays, during the manufacturing process are configured in such a way that their phase-frequency characteristic in linear mode corresponds (with certain maximum deviations, usually +/- 20о) to the curve specified in the specification. At the same time, their phase identity in the operating frequency range in linear mode is guaranteed. In the temperature range and at maximum output power, the phase response of the amplifiers may be somewhat varied, but these changes occur almost identically for the entire group of amplifiers operating with a multipath antenna array and have little effect on the parameters of the antenna array.

Thus, the normalized phase response of the amplifier allows, if necessary, the replacement of such amplifiers as part of a multi-beam antenna array without reconfiguring it.
