voltage-controlled signal limiter 5 to 1000 mhz technical data description the utl series consists of two voltage controlled signal limiters which cover the 5 to 1000 mhz frequency range. these thin-film limiters feature voltage program- mable output levels with input levels as high as +26 dbm. they have low vswr, low insertion loss, and excellent second- and third-harmonic suppression. recovery from fully saturated input levels is less than 50 nano- seconds. the utl models are provided in the to-8 package. utl-1001/1002 pin configuration to-8u features ? 0 to C13 dbm programmable output ? vswr less than 2.0:1 applications ? protection for detectors, mixers, and amplifiers ? cascadable gain control ? ew receiver circuits ? wideband system protection maximum ratings parameter maximum dc voltage +25.0 v continuous rf input power +26.0 dbm peak input power (3 m sec max.) +30 dbm operating case temperature C54 c to +125 c storage temperature C62 c to +150 c r series burn-in temeprature +125 c ground case ground v + rf out rf in weight: (typical) 2.1 grams schematic v+ rf in rf out
