FM RF Amplifier 8 Watt based 2SC1971

The above design is very simple FM RF amplifier 8W Watt based 2SC1971 VHF power transistor. The RF Amplifier PCB layout designed for FM broadband 88-108 MHz transmitters using microstripline technique. This 8W RF amplifier circuit provides an appropriate power boost for transmitters with an input of 500 mW.

RF Amplifier PCB
The PCB outline is 77 x 56 mm use FR-4 double sided photoresist epoxy pcb material for best results.

RF Amplifier Construction
All SMD components are 1206 types. Connect the bottom layer (groundplane) on several points (through via's) with the top layer of the PCB.

RF Amplifier Circuit 10MHz - 500MHz based BFR540

This is a RF amplifier circuit for 10Mhz - 500Mhz input signal. The RF amplifier is using single power transistor BFR540 as the main component to amplify the input signal. The BFR540 is an NPN silicon planar epitaxial transistor in a SOT23 plastic package. BFR540 featured with high power gain, low noise figure, high transition frequency and have gold metallization ensures excellent reliability.
