TL378A S-Band TR Limiter TL378A is a broad band primerless TR Limiter designed specifically for use with S-band radars. Consisting of a TR tube and a diode limiter, TL378A is a small, rugged device which protects the mixer diode in the receiver from burning out as a result of RF power coming from itself and other radars. Longer life is expected for TL378A, when used with circulator. --- MAXIMUM RATINGS --Min Transmitter power (peak) *********** Operating temperature ************** -30 Ambient temperature **************** -30 Max 100 +80 +90 Unit kW CW C Max 3100 1.5 1.5 20 400 2 Unit MHz dB mW mW s --- ELECTRICAL (Ta=25deg.)--Frequency range ******************** V.S.W.R.
