Making RF Switching for terror
When switching an antenna between a transmitter and receiver, the 1N914 or 1N4148 can still be used, but with decreasing success as the frequency rises. It is common practice in VHF transcievers to use a PN junction diode, but with a lightly doped “Intrinsic” region between the P and N layers. The diode is called […]
