termination - insensitive mixer, 1 - 500 mhz md - 161 fp - 2 v 3.00 features n third order intermodulation ratio is insensitive to port mismatches n conversion loss: 6 db typical midband n dc coupled if port n high level phase detector n impedance: 50 ohms nominal n maximum input power: 350 mw max. @ 25c, derated to 85c @ 3.2 mw/c n lo power +24 dbm max. n if port current: 50 ma max. n mil - std - 883 screening available description the unique design of the terminat ion insensitive mixer (tim) enables it to apply high reverse voltage to diodes during their ?off? phase, in the lo cycle. this allows for higher power level performance with minimum distortion. in addition the tim has internal loads that provide a good match and also absorb mixer generated lo frequency terms. combined, these features give the mixer its insensitivity to extern al mismatches, plus superior vswr. electrical specifications 1 : t a = - 55c to +85c parameter test conditions frequency units min typ max frequency range rf, lo ports if port 1 - 500 dc - 500 mhz mhz ? ? ? ? ? ? conversion loss 5 - 300 mhz 1 - 500 mhz db db ? ? ? ? 7 8 dc offset ? ? mv ? < 5 ? rf input 1 db compression 1 db desensitization dbm dbm ? ? +10 +7 ? ? isolation lo to rf lo to if rf to if 1 - 500 mhz 1 - 500 mhz 1 - 300 mhz 300 - 500 mhz db db db db 25 30 20 17 ? ? ? ? ? ? ? ? ssb noise figure within 1 db of conversion loss max. ? ? ? ? ? typical two tone im ratio with ? 10 dbm input, each tone and 60 mhz if 100 mhz 500 mhz db db ? ? 50 55 ? ? 3rd order intermodulation ratio degradation @ if vswr 3:1 db ? 3 ? dc polarity positive ? ? ? ? ? 1. all specifications apply when operated at +13 dbm available lo power with 50 ohm source and load impedance. this product contain s elements protected by united states patent number 4,224,572. pin configuration p in no. function pin no. function 1 gnd 5 lo 2 gnd 6 gnd 3 gnd 7 gnd 4 if 8 rf
