The Model PSPL5541A is a very broadband, coaxial bias insertion tee and DC blocking capacitor. It passes very fast rise pulses with a minimum of waveform distortion. Its rise time is only 8 ps. The frequency response is flat over many decades, and the -3 dB bandwidth extends from 80 kHz to beyond 26 GHz.

Key performance specifications
  • 80 kHz to 26 GHz
  • 8 ps rise time
  • 50 V, 100 mA
