Toptek Communications PA-80V-U Dual Band FM VHF/UHF Power Amplifiers

Toptek Communications PA-80V-U Dual Band FM VHF/UHF Power Amplifiers are attractive and flexible units intended for analog use with dual band handheld FM transceivers (HT), for Amateur 2M/70cm and VHF-UHF Safety, Business, Marine and Commercial applications. The PA80V-U operates over the 138-174 MHz and 430-470 MHz ranges with a nominal maximum power output of 80 watts on both bands. Typically, full output is achieved with 5 watts input from the transceiver. At a minimum input of 1 watt (maximum 10 watts), the amplifier automatically recognizes the transmitting frequency, switches to the appropriate band and signal path and keys the PA. The output power level can be set independently for VHF and UHF, preset to one of four steps: 25W, 45W, 65W, 85W. A multi-function eight LED bar graph meter measures Power Out, indicates power level settings, SWR (when Show SWR button is depressed), and indicates High SWR, Overdrive, Over-Under Voltage, High Temperature and PA Fail. Only FM Mode is supported, not DMR.

NOT compatible with DMR and P25 modes.

The Receive Low Noise Amplifier (RX LNA) can be turned on or off independently from the transmit Power Amplifier (TX PA). The LNA provides about 21db on VHF and 12dB on UHF.

Input and Output connectors are Type N female for the best SWR and lower losses. The PA-80V-U requires 13.8 VDC at a maximum of 13A.
