A 156 GHz single-stage GaAs dual-gate FET monolithic analog frequency divider with reduced input threshold power

摘要

Use of a dual-gate FET mixer and a rejection filter has resulted in a simplification of the circuit configuration and a reduction of the input threshold power, respectively, of an analog frequency divider MMIC. The device exhibits an input threshold power of 1.4 dBm in the operating frequency band from 14.2 GHz to 15.3 GHz. The circuit promises to be very valuable for the development of monolithic phase-locked loops (PLLs).
