This pallet has been designed for cost-sensitive applications from 20MHz to 250MHz requiring minimal footprint, high reliability and simple serviceability. It is very easy to replace the output transistor in this amplifier.
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 28-50V operation but gives full power at 48-50V. Using a lower voltage will result in lower output power. It is well suited as a driver stage and it will operate down to about 20 volts. RF output power can be adjusted by lowering the supply voltage.
As with any pallet you will need a heatsink, power supply and filter to use it.
- Frequency band: 55-88MHz, FM band 87.5MHz to 108MHz, 140-150, 175-225MHz or others on request
- Pout: 110-115W max
- Drive power required: 1W, varies somewhat with frequency
- Requires 28-50Vdc (requires 48V for full power)
- No bias adjustments or RF circuit tuning is required.
- Size: 40x48mm, 13mm high
You can find suitable filters here.
Suitable mains power supply are here.
A heatsink used for this pallet can be used as well, scroll to the bottom.
Warning: Do not exceed maximum supply voltage of 50V or damage will occur.
Note 1: Please use teflon 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!
