I’m sure I don’t have to […]

200mW FM Transmitter Project

Based on the output board from a 200 MHz TV repeater, I have finished building an amplifier for a cheap 1mW USB FM transmitter. The amplifier is based around the BFW16A which from the datasheet suggests is suitable for use from 40 to 860 MHz and can output around 150mW or so. It is housed […]
