M45204

Function of M45204 in radio-electronic equipment

The M45204 module is intended for operation in microwave signal paths where generation, preliminary amplification or processing of high-frequency signals is required. In onboard systems, such modules can be used in receiving or transmitting sections of radar, radio-navigation, altimeter or communication equipment. According to the supplied context, M45204 works in the L-band frequency area and may be installed in the receiver section of RV-3 radio equipment. The exact circuit role depends on the parent unit and system documentation.

M45204 in radio altimeter equipment

M45204 is referenced as a component used in aircraft radio altimeter systems, including RV-3, RV-4 and RV-5 context references. In such equipment, microwave modules are used in the radio-frequency chain to form, receive, amplify or process signals related to height measurement. The module may support the operation of the receiver path or RF section of the radio altimeter. Since radio altimeter versions and internal block structures differ, applicability must be confirmed by the specific equipment manual, wiring diagram and installed unit configuration.

Frequency range and microwave construction

The supplied context indicates that M45204 operates in the 1.9–2.1 GHz frequency range, which belongs to the decimeter / L-band microwave region. The product is described as a hybrid-integrated microwave module manufactured in a sealed metal-ceramic or metal housing. This type of construction is used to protect sensitive high-frequency circuitry from vibration, humidity, contamination and mechanical stress. The module is associated with technical specifications bSh2.017.120 TU and production by NEVZ-Soyuz according to the source context.

Operating and storage context

As an aviation microwave component, M45204 is intended for demanding operating conditions typical of onboard radio-electronic equipment. The source context indicates resistance to vibration and linear loads, operation over a wide temperature range and use under reduced atmospheric pressure conditions. M45204 may be found as first-category or long-term stored aviation inventory, including Soviet and post-Soviet production batches. Before use, inspection of packaging, seal condition, passport data, production year and bench-test records is strongly recommended.

Identification and ordering of M45204

Before ordering M45204, the buyer should confirm the exact designation, parent equipment, required condition, quantity and documentation set. It is especially important to clarify whether the module is required for RV-3, RV-4, RV-5 or another radio-electronic system. The item may be needed for repair of a radio altimeter receiver, restoration of microwave signal paths, replacement of a failed RF module or spare parts stock. For acceptance, the product passport, technical specifications reference, serial number and test documentation should be checked.
