60_W_LINEAR_FOR_432_MHz
Suitable for mak-ing DX contacts through Oscar satellite, as well as for tropo and local contacts, using CW or SSB. Motorola MRF5176 transistor provides drive to MRF306 output stage, giving sufficient output over range of 430-450 MHz. Requires 1-3 W RF input. Microstrip conductors W1-W3, each 0.077 wavelength long, provide wideband matching and high efficiency. Article gives dimensioned layout for printed-circuit board and all construction details.-J. Buscemi, A 60-Watt Solid-State UHF Linear Amplifier, QST, July 1977, p 42-45.
