The design and performance of two different monolithic 2-18-GHz matrix amplifiers are discussed. The first module, optimized for gain and return loss, yields gains of G=15.5±0.9 dB and a maximum return loss of RL=-12.0 dB. When these modules are cascaded to form a two- or three-stage amplifier, gains of G=31.4±1.4 dB and G=43.2±1.8 dB, respectively, are measured. For the second unit, designed for low noise and gain, noise figures of NF=4.15±0.85 dB and gains of G=17.1±1.25 dB are achieved
