Abstract:

Two UHF high-power amplifier modules were developed, utilizing thin-film hybrid integrated circuit technology and a modular building block approach. Several functional integrated power amplifier stages were cascaded and paralleled, utilizing 3-dB quadrature couplers to achieve the high power gain and power output. The power amplifiers were designed to operate over the 225- to 400-megahertz frequency range and provide an objective power output of 80 watts peak power. Each functional integrated power amplifier stage utilizes a self-contained variable DC-bias circuit to achieve linear operation. This circuit provides the appropriate change in base-to-emitter forward bias at different power output levels of the RF amplifiers. The UHF power amplifier modules were designed specifically for amplitude-modulated systems where high peak envelope power is required. Author
