Ultra-Broadband Bias Tee
PSPL5542 Datasheet
The Model PSPL5542 is an ultra-broadband, coaxial bias insertion tee
and DC blocking capacitor that passes ultra-fast pulses with very low
waveform distortion. Its rise time is only 7 ps, and its frequency
response is flat over many decades from 10 kHz to beyond 50 GHz. It
is available with either 2.92 mm (40 GHz) or 2.4 mm (50 GHz)
connectors. Its small package makes this bias tee ideal for 40 Gbit
data systems as well as broadband RF and microwave applications.
