MVTU19

The MVTU19 low-noise high-frequency transistor amplifier unit is designed to replace the morally and technically obsolete high-frequency tube amplifiers ESU-5, ESU-8 in the P19 radar.

The unit has a built-in protective device for protection against synchronous and asynchronous impulse noise, which operates in the limiting mode both from the start pulse or BLANK, and in the self-limiting mode.

The unit has a built-in temporary gain control (TDC) to suppress interference from reflective local objects.

Application of MVTU19 provides:

The module has good maintainability without deterioration of electrical parameters and low repair cost as opposed to traveling wave tubes.
