I’ve been selling these distribution boxes all over the world and have been really pleased with the interest. I decided I would build another one for myself for use with the 48v SSPAs I have. I uprated the resistors and the capacitors. Here is the finished result.
Last week I installed a bandpass filter which I purchased from http://www.fmbroadcastparts.com/ into my 500w SSPA.
Its design is optimised for use with 600W & 800W & 1KW pallet amplifiers and can be mounted on the same heat sink as the pallet. I bolted mine on the front panel of the linear which is made of aluminium.
Only first class RF Microwave components are used on a silver plated Rogers Teflon PCB with silver plated copper inductors and Teflon PCB capacitors are used to minimize internal loss and best possible harmonic suppression.
Although available in 2 versions, coaxial connections or N female connectors, I chose to use the coaxial connection version.
