MVTU67A

The MVTU67A low-noise high-frequency transistor amplifier unit is designed to replace morally and technically obsolete UV-67A traveling-wave lamps in the “Osa” ADMS.

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 MVTU67A provides:

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