HBRPA50, Low Cost Linear HF Power Amplifier 50 Watt (Final 2 x IRF530 PushPull)
BRHFPA10 is the HF Power Amplifier using low cost MOSFET (2 X IRF530) on driver and final. The Amplifier output depend on supply voltage and bias setting.
Its using generic design off push pull amplifier.
*. This unit is assembled and tested on 40m (7MHz), up to 25 watt output with 1-2 watt input, operate on 12V power supply, with dummy load
*. You may change voltage supply using step up (I do not sell the step up), up to 18V and get up to 50 watt output, but please used proper heat-sink and fan
*. The Power output will decrease on higher band
*. Beware when you want to adjust the bias voltage, improper operation may damage the MOSFET
*. the aluminum heat-sink on the picture is for demo/reference not include in packet
