Waveform Generation Using a Broadband Balun, Z-Matched Pick-Off Tee and Resistive Power Divider

Thu, 31 Mar 2022 16:24:32 -0400

This application note demonstrates use of HYPERLABS’ broadband coaxial components as general-purpose analog signal processing components for the generation of novel time-domain waveforms. The HL9474 6 dB resistive power divider and HL9462 Z-matched pick-off tee are demonstrated as lossy broadband summing networks. The HL9404 broadband balun is demonstrated as a pulse inverter and 180° signal splitter. The HL5567 PAM4 encoder is used to combine two pseudorandom binary or bit sequence (PRBS) patterns into PAM4 signaling. Utilizing the basic arithmetic functions of addition, inversion and subtraction, together with a time delay, a wide variety of novel broadband waveforms are generated.

This application note builds on prior work reported in Picosecond Pulse Labs (PSPL) Application Note AN-20a^_[1]. In the referenced note, Jim Andrews, Ph.D. used PSPL pulse generators together with PSPL passive components to produce a variety of novel waveforms. A similar set of waveforms are demonstrated at higher bandwidths in this application note utilizing HYPERLABS’ industry leading broadband passive components.
