RECEIVER BUILDING BLOCKS

  
This amplifier has about 20dB of gain, bandwidth of 100MHz and noise figure of about 7dB. The output transformer is 8 turns bifilar wound on a ferrite core. Use a medium power UHF transistor 2N5109, 2N3866, 2N4427 or similar. The transistor will need a small clip on heatsink. This amplifier is suitable for use in the front end of a HF receiver or as a post mixer amplifier following a diode mixer (see below.)
