TOPTEK 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.
These amplifiers provide 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 Amateur UHF operations.
THIS UNIT WILL ONLY BE SOLD TO QUALIFIED AMATEUR RADIO OPERATORS AND MUST ONLY TRANSMIT ON AMATEUR FREQUENCIES. THE PURCHASER MUST PROVIDE PROOF OF THEIR AMATEUR RADIO QUALIFICATION. IF YOU DON'T HAVE AN AMATEUR RADIO (HAM) LICENCE PLEASE DON'T PURCHASE OTHERWISE WE WILL REFUND YOUR PURCHASE.

WARNING: The transistors in the RF finals are expressly not covered by the manufacturers warranty. We do not accept 'change of mind', 'upgrade', 'not quite what I wanted' or 'swap' returns so be careful this is the model you want before purchasing.
Please Read Before Using:
- Do not use outside of the specified frequency ranges as damage may occur.
- Care needs to be taken that the antenna you are connecting to is in good condition and the VSWR is less than 1.5:1 on the frequency you are transmitting on.
- For higher power amplifiers (100+ watts) we recommend a single band antenna tuned to the frequency you are transmitting on.
- Never use an amplifier to attempt to compensate for a poorly tuned, high SWR antenna, for poor quality coaxial cable or connectors.
- We strongly recommend not using a power amplifiers with an indoor or loft antenna.
- Check the transmit power immunity of your vehicle if vehicle mounting as this may damage the electronics and/or disable your vehicle or functions of your vehicle.
- Be certain that the supply current from your power supply is ample for the peak current draw of the amplifier otherwise damage to the amplifier may occur.
- Be very careful when operating at high power and keep well clear of the transmitting antenna.
- Always check your antenna and feedline performance with an SWR meter on low power before increasing power to maximum.
- Do not overdrive the RF input of the amplifier.
- Do not operate the amplifier without a 50 ohm antenna or overrated dummy load connected to the antenna output.
- Do not operate your amplifier in hazardous environments - ie service stations, mines, etc
- Regularly or continuously test your antenna and feed line SWR for unexpected performance issues.
- Disconnect the antenna if lightning or storm activity is occurring nearby.
- Do not touch the antenna or exposed antenna connections when transmitting.
- Stop transmitting immediately if a fault appears.
