SMG1

The SMG1 is designed as one kind of signal limiter with a discrete hybrid design which uses thin film manufacturing processes for accurate performance and high reliability.This design uses Schottky bridge quad and anti-parallel diodes,which provide consistent limiting levels over a broadband frequency range.Both TO-8 and SMTO-8 packages are hermetically sealed,and MIL-STD-883 environmental screening is available.

Features of the SMG1 are:(1)available in surface mount;(2)low insertion loss at low input levels:2.0 dB to 1000 MHz(typ.);(3)wide band performance;(4)low distortion:-25 dBc(typ.) at Vcontrol=+15 V.The absolute maximum ratings of the SMG1 can be summarized as:(1)storage temperature:-62 to +125;(2)case temperature:+125;(3)DC voltage:+18 V;(4)continuous input power:+20 dBm;(5)short term input power(1 minute max.):200 mW;(6)peak power:1 W;(7)"S" series burn-in temperature(case):+125.

The SMG1 electrical specifictions can be summarized as(25):(1)frequency:5-2200 MHz;(2)insertion loss @ Pin<-20 dBm(max.):2.0 or 3.0 dB;(3)input VSWR(max.):<1.8:1;(4)output VSWR:1.7:1 or 2.0:1;(5)output limiting level @ PIN=+20 dBm(max.):2.5 or 6.5 dBm;(6)bias current(max.):10 mA;(7)control voltage:0 to 15 volts;(8)control current(max):4 or 7 mA.
