The PSPL5550B 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 20 ps with a -3 dB bandwidth extending from 100 kHz to 18 GHz. The PSPL5550B will safely carry 500 mA of DC current. However, core saturation limits the low frequency response at DC currents above 50 mA. Key performance specifications 100 kHz to 18 GHz 20 ps rise time 50 V, 500 mA
