The amplifier provides 10 dB of gain from 10-600 MHz and has a 1.5-to-1 match at 50 ohms. The BFR91 has a 1.5 dB noise figures at J, 500 MHz. The circuit requires 13.5 Vdc at about 13 mA. Keep the leads on the 150 pF emitter bypass capacitor as short as possible.The 16 nH coil is 2.5 tums of #26 enamel wire on the shank of a #40 drill. The 93 nH inductor is 10 tums of the same material.
