The Linear Amp UK 64-500 is an uprated unit based on the 300W amplifier. The Linear Amp® 64-500 uses a ART700FH LDMOS.

The Linear Amp UK 64-500 is an ideal match for rigs like the Icom IC-7300 delivering up to 500W on 50MHz and 300W on 70MHz. These levels allow the full UK legal limit on both bands with a little over to cover feeder loss to your antennas.

The amplifier can be specified with a rear panel 0dBm SMA socket for predistortion linearisation for use with the latest generation of SDR's.

Designed to fill a market gap between the low power outputs of transverters and smaller rigs and the 1kW plus amplifiers that not all users want or can afford the Linear Amp® range combines low drive requirements with instant on solid state performance in a compact stylish package.

The Linear Amp UK 64-500 RF section uses a single LDMOS device for high performance and maximum ruggedness. This, combined with built in protection for overdrive, high SWR and over temperature ensures solid reliable performance at high outputs for long periods. The unique RF design architecture has resulted in fully automatic DUAL BAND capability giving both 50-54MHz and 69-72MHz coverage without any bandswitching.

A complete turnkey solution incorporating a complete 50V linear power supply so no external PSU is required.
