The Tektronix/Picosecond Pulse Labs 5542-202 is an ultra-broadband bias tee that injects or extracts DC bias current from high-frequency signal paths while preserving signal integrity across demanding applications. Operating from 10 kHz to beyond 50 GHz with a 7 ps rise time, this 50 Ω component delivers insertion loss below 2 dB at 50 GHz and maintains greater than 50 dB isolation between AC and DC ports above 100 MHz. The design minimizes waveform distortion in ultra-fast pulse systems, making it essential for 40 Gbit data communications, broadband RF/microwave work, and precision signal manipulation in research environments.
