100W with low voltage 12-15V 

This 100W pallet has been designed for applications requiring low supply voltage (10-15V), high efficiency and excellent wideband frequency response. It can produce full output power @ 15V with about 2W of drive power across entire band even at band edges. Peak power at band center is well above 100W.

Each pallet amplifier we sell is designed and tested using vector network analyzer and spectrum analyzer. Our amplifier products are manufactured using an automatic surface mount assembly process. This pallet is optimized for 10-15V operation and is perfect for battery-powered mobile applications and solar powered applications. Using a lower voltage will result in lower output power. It will operate down to about 10 volts with reduced output. As with any pallet you will need a heatsink, power supply and filter to use it. More information is available in the included amplifier data sheet.

Any of our exciters capable of producing at least 2-3W is suitable to drive this pallet amplifier. Two or more of these pallets can be combined to create 200W  or more from battery power. Using solar panels for your radio transmitter? This might be your dream solution.

Technical specifications:
– FM band, 87.5MHz to 108MHz, will work from 80 – 120MHz at reduced power (also available for 81, 144MHz and other frequency bands, email for info)
– Input/output 50 ohms.
– Pout: >100W even at band edges
– Drive power required: ~2W
– Requires 10-15Vdc (100W/8A)
– No bias adjustments or RF circuit tuning is required.
– Size V1 100W: 48x102mm, ~35mm high

You can find suitable filters here.
Suitable mains power supply are here.
Warning: Do not exceed maximum supply voltage of 15V or damage will occur.

Note 1: Please use PTFE coaxial cable for RF input (RG178 is perfect) and output (RG178 or RG142 are perfect) connections, this makes it possible to have very short leads without burning the coax. Keep the coax leads as short as possible (few mm at most). Also keep leads short on connectors, this  N female flange for RG142 or .141 semirigid – easy install is perfect!

Note 2: A small heatsink is definitely needed!

Note 3: The actual product differs from the one on the photo. We do not have photos yet of this pallet.
