General Description

SAC1001 is a GaAs MMIC envelope detector die covering DC to 20 GHz, built on a Schottky diode process with through-substrate vias. It offers 30 dB of dynamic range with ±1 dB flatness, 1.6:1 input VSWR, 50 ns rise time and 300 ns fall time.

Its second, matched diode (Vref) lets you read Vdet differentially and cancel temperature drift. It draws 2.5 mA, the 1.25 x 1.25 x 0.1 mm die is BCB protected, and max input is +18 dBm. Handy for transmit power leveling in radar, ECM, radio and test gear.
