Transistor amplifier (power amplifier) UM-2 are made for communication and telecommunication systems, also it can be used in a preliminary or final amplifying stage in 10 cm wave band transmitters.

The power amplifier is made as functionally independent hermetically sealed module with coaxial input and output in 3,5 / 1,5 mm channel. The bottom of the module package is not painted and is designed to be mounted on the heat sink. Overall and mounting dimensions of the modules allow to use them instead of the previously manufactured amplifiers M42144 (Russia made).

The power amplifier UM – 2 is used in new generation radars 36D6 and 1L220, it can be also used in previously manufactured radars ST68 (19G6) instead of obsolete amplifiers M42144 as well as in radars being developed.
