This amplifier has VHF (very high frequency) and UHF (ultra high frequency) response, you can use it for receiver booster for example. Here is the schematic diagram of the circuit:

HF amp. 40 500MHz circuit schematic

The current consumption is very low, under 20 mA for 14V voltage supply.  Lower current consumption can be achieved if we use 10V power supply, the current consumption would be under 14 mA. [Circuit’s schematic diagram source:]
