control devices: mlp 7100 series limiter diodes description the micrometrics mlp 7100 series limiter diodes are specially processed pin diodes with a thin intrinsic region designed for use in passive or active limiters over the entire range of fre- quencies from 100 mhz to beyond 20 ghz. the different ??region thick- nesses and capacitances provide vari- able threshold and leakage power lev- els and power handling capability. applications the mlp 7100 series limiters are for use in waveguides, coax, microstrip or stripline. single or cascade devices may be used depending on power levels. r s r s r s 2 50 50 coil for ground return high power equivalent circuit 2 34 features low loss greater bandwidth fast turn on time packaging chip, glass, ceramic, surface mount typical performance 50 50 diode chip +50 +40 +30 peak power output (dbm) peak power input (dbm) +20 +10 0 +10 +20 +30 +40 +50 +60 +66 mlp7130 mlp7110 mlp7140 MLP7100 mlp7120 50 0 +3 +6 2 4 6 8 10 12 14 16 18 +8 50 diode chip mlp 7100 series mlp 7100-7140 series frequency (ghz) leakage power above 1.0 ghz (db) control devices micrometrics, inc. 136 harvey road, building c, londonderry, nh 03053 voice: 603-641-3800, fax: 603-641-3500, internet: www.micrometrics.com, e-mail: serv@micrometrics.com
