Toptek Communications PA-350V VHF 135-165 MHz 350W Power Amplifiers

Amplifier, VHF, 2m, 135-165 MHz, 350W Out Max., 7.5 or 15W In, FM, SSB, CW, RX Preamp, LCD Meter PWR IN & OUT, Menu PTT IN, Type-N, 13.8Vdc@50A.,

Overview

The PA-350V is is an advanced and versatile high-power Solid State linear amplifier designed for Amateur Radio 2 Meter FM, SSB and CW operations and Commercial VHF. A large, easy-to-read green backlit Alphanumeric LCD provides simultaneous digital input power, output power and SWR readings. Front panel button actions and specialized, user-defined function readouts and menu selections are displayed, including incremental 100, 200, 300 and 350W power output settings. This VHF amplifier* delivers approximately 300 watts output with only 5 watts input from an HT or 350 watts maximum output with a VHF mobile. The PA-350V has two selectable input ranges, Low 15W max and High 30W max, achieving 350 watts output with either 10 watts input or 15 to 25 watts input, to accommodate almost any VHF transceiver. Multiple protection circuits, a Receive Low Noise Amplifier (LNA) with a bandpass filter, RF sense or PTT keying (required for SSB/CW) and thermostatically controlled fans are some of the great features of this top-of-the-line Toptek amplifier. True 50 ohm Type-N RF connectors maintain the highest efficiency to the feedline and antenna.

*Requires 13.8 VDC @ 50A max. (External power supply not included).

Features of the Toptek PA-350V Amplifier:

Wideband Solid State VHF power amplifier delivers over 350 watts of RF output typically with only about 8 or 15 watts of drive power
