PSPL5575A 12 GHz Bias Tee Datasheet

PSPL5575A Datasheet

The PSPL5575A is a broadband coaxial bias insertion tee and DC blocking capacitor designed to pass fast rise pulses with minimum waveform distortion. The rise time is 30 ps with a -3 dB bandwidth extending from 10 kHz to 12 GHz. The PSPL5575A will safely carry 500 mA of DC current. However, core saturation limits the low frequency response at DC currents above 20 mA.
