PSPL5543 Datasheet

The PSPL5543 is an ultra-broadband, 500 mA current, coaxial bias insertion tee and 100 V DC blocking capacitor that passes high bandwidth pulses with very low waveform distortion. Its rise time is only 7 ps and its frequency response is flat over many decades from 20 kHz to beyond 50 GHz.

Key performance specifications
  • 25 kHz to >50 GHz
  • 7 ps rise time
  • 100 V, 500 mA

Typical performance

The following figures show the linear sweep from 40 MHz to 65 GHz. The AC connector is input (port 1) and the AC + DC connector is output (port 2).

The following figure shows the S21 insertion loss.


The following figure shows the S11 return loss.


The following figure shows the S22 return loss.
