The MVTU98A low-noise high-frequency transistor amplifier unit is designed to replace morally and technically obsolete traveling-wave tubes UV-98A in 9S32 (S-300 air defense missile system).
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 MVTU98А provides:
The module has good maintainability without deterioration of electrical parameters and low repair cost as opposed to traveling wave tubes.
