PPD-2001

The PPD-2001 is designed as one kind of wideband-sensitive threshold detector which provides efficient and accurate RF level measurement at critical system points.It cantains a schottky diode detector,compatator and a temperature compensated voltage reference assembly.The unit is built with chip and wire construction on a thin-film substrate for small size and ruggedness.

The PPD-2001 has four points of features:(1)wideband;(2)temperature compensated;(3)low VSWR and (4)small size,easy to use.It can be used in broadband EW receiver,level control and signal monitoring.And the absolute maximum ratings of it:(1)DC voltage:+/-22 volts;(2)continuous RF input power:+20 dBm;(3)operating case temperature:-55 to +125;(4)storage temperature:-62 to +150;(5)"R" series burn-in temperature:125 and (6)temperature rise(no load):9;(7)temperature rise(output short circuit):30.,

Some information about the electrical specifications of PPD-2001 can be summarized as:(1)frequency:20 to 2000 MHz;(2)VSWR(small signal) max:1.5:1;(3)sensitivity,Pin=0 dBm,min:1.0 V;(4)power flatness,referred to input max.:+/-0.1 dB;(5)tangential sensitivity:-38 dBm;(6)output resistance:15;(7)output offset drift:+/-5 mV;(8)RF to video siolation:40 dB;(9)rise time:2.0 us;(10)supply voltage:+/-15 VDC and (11)supply current:2.0 mA.
