A comparison is made between the performance of the MMIC matrix and distributed amplifiers. It has been shown that based on the analytical formulations, in most typical cases a cascaded dual stage distributed amplifier has more gain than that of a two-tier matrix amplifier with the same number of transistors; however the difference is not significant. Results of the analytical approach are then compared with the simulated and the measured results and a good agreement between the results has been obtained. Then other scattering parameters of the matrix and distributed amplifiers have been compared.
