These UHF diodes give a full capacitance range of 20 to 200pF at 4 volts bias, ultra-high Q and excellent large signal handling capabilities, along with a 2 to 1 capacitance ratio by tuning from 9 to 20 volts of reverse bias. Closely matched sets of all VHF diodes are available along with "A" suffix versions having 5% capacitance tolerance at 4 volts of reverse bias.
