NJS6939 X-Band Diode Limiter NJS6939 is designed for the high power limiter of radar system. It features a small size operable at any frequency between 9.00GHz and 9.20GHz. This diode limiter consists of the two stage self biased limiter diodes and no external trigger and no bias is required. ---- MAXIMUM RATINGS ---Maximum handling power(peak) Continuous handling power(peak) Ambient temperature Min -30 Max 8 4 +90 - - RF pulse width ---- ELECTRICAL ---- <at 25 degree centigrade> Min Max V.S.W.R.(Note 1,4) 1.5 Insertion loss(Note 1,4) 1.5 Flat leakage power(Note 2,4) 150 Spike leakage power(Note 2,4) 600 Recovery time(Note3,4) 0.5 Note: 1.
