3026(A-034-4-16)

Power Amplifier and Analog Switch Board 3026 is a functional electronic board designed for operation as part of airborne indicator units A-034-4-16, A-034-4-22, and A-034-4-11. The board is included in the equipment set of the A-037 radio altimeter and operates as an internal module of the indicator signal processing and control circuitry.

The 3026 board is intended for amplification of electrical signals and analog switching between signal paths in accordance with the operating logic of the indicator. Within the indicator unit, it performs functions related to signal conditioning, controlled switching, and interaction between measurement and indication circuits required for correct display of radio altimeter data.

The board is not a standalone device and is designed exclusively for operation as part of indicator units A-034-4-16, A-034-4-22, and A-034-4-11 included in the A-037 radio altimeter system. Electrical operating modes, functional characteristics, and performance parameters of the board are defined at the system level and are regulated by the technical documentation of the indicator and the radio altimeter.

Structurally, the Power Amplifier and Analog Switch Board 3026 is manufactured as an electronic printed circuit board installed inside the indicator housing. The design ensures electrical and functional compatibility with other boards of the indicator and stable operation under specified operating conditions.

According to the product passport, the section “Basic Technical Data” for the 3026 board is not specified. Reliability parameters, service life, and storage life correspond to those of the A-037 radio altimeter and its associated indicator units.

Operation of the Power Amplifier and Analog Switch Board 3026 is permitted only in compliance with the applicable technical documentation of the indicator units and the radio altimeter system.
