Abstract :
The circuit and the measured performance of the first 2 × 2 matrix amplifiers are discussed. Gains of 18.6 ± 0.4 dB at noise figures of NF ¿ 4.4 dB have been achieved across the 6-18 GHz frequency band. When cascading two modules, gains of G = 38.5 ± 1.1 dB at maximum reflection losses of ¿11.0 dB (VSWR ¿ 1.79:1) were recorded. These and other experimental results, such as performance characteristics over temperature and harmonic output powers will be addressed.
