High Power Broadband Antenna Switch Circuit Design
High Power Broadband Antenna Switch Circuit Design - The following circuit shows an example of a high power boad-band antenna switch which is designed to operate over the 10 to 100Mhz band.
The switch control 1 KW transmitter power with excellent distortion performance (IM3<-80dBc). The forward bias into Bias Terminal 1 is 1 Ampere, for low power dissipation in the transmitter diode and reverse bias of 500 Volts so that excessive RF current does not flow in the OFF state.
You might use the UM2010 (2 to 30 MHz) series for HF Band, and UM2310 series for MF Band (0.3 to 3 MHz).
