Reference No.: DS-TL378A Rev.: 03E Sheet: ■ GENERAL DESCRIPTION TL378A is a broad band primer less 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 it and other radars. Longer life is expected for TL378A, when used with circulator. ■ ELECTRICAL CHARACTERISTICS < at 25 ºC > PARAMETERS MINIMUM MAXIMUM UNITS Frequency range 3000 3100 MHz Insertion loss (Note 1,3) 1.5 dB Flat leakage power (Note 2,3) 20 mW Spike leakage power (Note 2,3) 400 mW Recovery time (Note 2,3) 2.0 μs Note 1: Measured at input power level 0.1mW CW.
