Toptek Communications PA-150U UHF 430-470MHz 150W RF Power Amplifiers

Toptek Communications PA-150U UHF 430-470MHz 150W RF Power Amplifiers are very capable, efficient 2-stage UHF linear amplifiers for FM, SSB, CW and Digital modes of operation. This amplifier provides over 150 watts of output with only 2 to 5 watts input drive, dependent upon UHF frequency from 430 to 470 MHz, with slightly lower output from 460 to 470 MHz. An attractive and useful front panel with a digital multi-meter and push-button controls, and a heatsink chassis with cooling fans, makes this amp perfect for commercial or Amateur UHF operations. PA-150U UHF Amplifiers have these important features: - Front panel digital metering of input and output power and SWR - Automatic Fault protection for SWR over 2:1 - Built-in low-noise receive preamplifier, with band pass filtering; nominal 10 dB gain - PTT Input for proper operation in SSB, CW and Digital Modes - RF sense keying for FM mode (PTT connection not required for FM) - Mode switch for automatic SSB delay and peak power metering - Settable FM mode power output: LOW, Medium 100W and High 150W steps - Ultimate SSB maximum 5W PEP input, 170W PEP output (maximum peak power) - Amplifier standby maximum bypass power: 50W - Type N female connectors, 50 ohm Input and Output - Permanently attached 24 in. (60cm) DC power cable, unterminated - DC Input: 13.8 Vdc @ 30A maximum at full output 150W (10.5 to 14.8 Vdc operational range) - Dimensions (WHD): 7.25 x 3.50 x 12.52 in. (184 x 89 x 304mm) - Weight: 6.6 lbs. (3.0 kg) - NOT compatible with DMR and P25 modes NOTE: Rear panel accessory jack (4-pin mini-DIN) is provided for the accessory REMOTE Control Panel, TEK-REMOTE.
