Module of MVTU01.M1 low-noise high-frequency transistor amplifiers are designed to replace worn out and outdated UV-74J(I) traveling wave tubes (TWT) in the P-37 radar.

  

The module has a built-in protection device to protect against synchronous and nonsynchronous pulse jamming, operating in the restraint mode from both the trigger pulse or “BLANK” pulse, as well as in the self-restraint mode. The module has a built-in device of time-corrected gain (TCG) for interference suppression from reflecting local objects.

Application of MVTU01.M1 provides:

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