PSPL5545 20 GHz Bias Tee Datasheet

PSPL5545 Datasheet

The PSPL5545 Bias Tee and DC Block is a broadband, coaxial bias insertion tee and DC blocking capacitor. It passes fast rise pulses with a minimum of waveform distortion. The rise time is 12 ps. The frequency response is flat over many decades, and the -3 dB bandwidth extends from 65 kHz to 20 GHz.
