M45110-1 is a microwave receiving module designed for operation in airborne radio altimeter systems. The module forms part of the radio-frequency and microwave circuitry and is intended for reception and processing of microwave signals reflected from the underlying surface.

The M45110-1 receiving module is included in the radio component set of the A-037 radio altimeter and is installed in the following equipment configurations: A-037-1A, A-037-1V, A-037-1G, as well as in the PP-5M receiver. Within the radio altimeter system, the module performs the function of receiving the microwave signal from the antenna system and transferring it to subsequent signal processing stages.

According to the product passport, the module provides amplification and frequency-selective processing of the received signal within the specified operating frequency range. The electrical parameters of the module ensure stable operation when used together with the transmitting and processing units of the radio altimeter.

Structurally, the M45110-1 module is manufactured in a metal shielded housing and is equipped with coaxial microwave connectors for signal input and output, as well as electrical connectors for power supply and control circuits. The design ensures protection against external electromagnetic interference and stable characteristics under operational conditions.

The module is intended for operation in accordance with the requirements of the technical documentation and operating instructions specified in the product passport. Reliability, storage life, and minimum operating life are established by the manufacturer and defined in the passport documentation.
