Abstract :
A highly integrated wide-band MMIC RF-source using the heterodyne frequency conversion scheme is presented in this paper. Two oscillators, a mixer, and three corresponding buffer amplifiers find place on a MMIC chip with dimensions of 3.0 × 1.8mm2 manufactured using a commercially available 0.25 ¿m pHEMT process. The circuit provides RF power within a wide range of f = 3.5 - 6.5GHz.
