Low-noise broadband amplifier

  
The amplifier provides 10 dB of gain from 10-600 MHz and has a 1-to-l match at 50 ohms. The BFR91 has a 1 dB noise figures at 500 MHz, The circuit requires 13 Vdc at about 13 mA. Keep the leads on the 150 pF emitter bypass capacitor as short as possible. The 16 nH coil is 2 turns of #26 enamel wire on the shank of a #40 drill

The 93 nH inductor is 10 turns of the same material.
