The recommended supply range is 30-50Vdc. Each individual MRF300 LDMOS transistor is specified at 330W output over a 1.8-250MHz working frequency range, a maximum 28dB of gain and over 70% efficiency. The common TO-247 package is used, with the source connected to the tab. Luckily, the manufacturer made it easy to design the PCB layout for such a thing by offering two versions (the MRF300AN & MRF300BN) that have mirrored pinout. To achieve the target of 600W output while also minimizing the level of even-number harmonics, a “push-pull” configuration of two transistors is used.

This is also my entry to the NXP Homebrew RF Design Challenge 2019. Second place winner A 600W broadband HF amplifier using affordable LDMOS devices (For more information visit: ) This project is meant to demonstrate the capabilities of the MRF300 transistors as linear broadband devices in the 2-50MHz range and to be used by radio amateurs as a starting point for a medium-high power amplifier. and 310g weight including fan and heat sink. The design dimensions of the PCB is 5x5 cm (2x2 in). Maximum power supply 50V to 4A, with a Voltage Standing Wave Ratio of 1.5:1 maximum. Maximum output power of 100W up to 30MHz and 70W up to 50MHz. (For more information visit:NXP MRF-101 - RFPowerTools ) It is an amplifier with a bandwidth of 1.8MHz to 54MHz.

First place winner An MRF101AN broadband amplifier design with 1 W Input, 100 W Output 1.8-54 MHZ Amplifier deck. We appreciate the dedication and enthusiasm from the community that made this contest a success. NXP received numerous creative submissions in this competitive Homebrew RF Design Challenge.
