TL393 X-Band TR Limiter TL393 is a broad band primerless TR Limiter designed specifically for use with X-band radars. Consisting of a TR tube and the two stage diode limiter, TL393 is a small, rugged device which protects the mixer diode in the receiver from burning out as a result of RF power coming from other radars. --- MAXIMUM RATINGS --Min Transmitter power (peak) ··········· Operating temperature ·············· -30 Ambient temperature ················ -30 Max 100 +75 +90 Unit kW °C °C Max 9500 1.5 2.0 25 400 2 Unit MHz dB mW mW µs --- ELECTRICAL (Ta=25deg.)--Frequency range ···················· V.S.W.R.
