Paper Abstract

Details of the design, fabrication, and measured data for three InGaAs HEMT broadband feedback amplifiers are presented. Each amplifier was designed for octave bandwidth operation, but exhibits good performance over slightly larger bandwidths: 2-7 GHz, 5-11 GHz, and 9-19 GHz. The circuits feature compact size, low noise, and high yield. Each circuit measures approximately 2.5 mm x 1.5 mm. Maximum noise figure measured 2.1 dB with 11.8 dB minimum gain for the low-band amplifier, 1.9 dB with 9.9 dB gain for the mid-band amplifier, and approximately 2.5 dB with 8.3 dB gain for the high-band amplifier. RF yields of greater than 70 percent have been achieved.
