Above schematic diagram is the circuit of VHF pre-amplifier for FM broadcasting (frequency 88MHz-108MHz, band II)The circuit is working with two 2N3819 FET's in cascode configuration. The lower FET works in common source mode, while the upper FET, works in common gate, realising full high frequency gain. The bottom FET is adjustable allowing a peak for a .......

ICs that in the past were far too expensive for the hobbyist tend to be more favourably priced these days. An example of this is the AD8099 from Analog Devices. This opamp is available for only a few pounds. The AD8099 is a very fast opamp (1600 V/ms) and has high-impedance inputs with low input capacitance. The bandwidth of the opamp is so large that at 100 MHz it still has a gain of nearly 40. This means that this opamp can be used to create an RC oscillator. The circuit presented here realise.......

Parallel Port VHF FM Receiver - Use it to monitor the 144-148MHz amateur band, the 132-144MHz band or the 118-132MHz band. This neat little FM receiver is controlled by your PC and tunes the 144-148MHz amateur band. Alternatively, just by changing the software, you can use it to tune the 132-144MHz band for weather satellite frequencies or, with just a few hardware changes, the 118-132MHz band........
