8 to 23 GHz, 500° Time Delay/Phase Shifter

摘要

Hittite Microwave Corp. has developed a new broadband time delay/phase shifter that is ideal for clock chain and skew adjustment in 10G-RZ, 40G/100G RZ-DQPSK fiber optic applications. The HMC877LC3 is one of the first time delay/phase shifter products to provide 0 to 500° (1.4 Unit Interval) continuously adjustable delay over a wide 8 to 23 GHz frequency range. The device provides a differential output voltage with constant amplitude for single-ended or differential input voltages above the input sensitivity level. A control pin may be used to adjust the output voltage swing between 500 and 900 mVp-p.
