I apparently had a folder of images prepared for technical grade shitposting that were going unused so it’s time for a SHITPOSTING FESTIVAL OF LIGHTS
This shitposting festival made possible by the PTek corporation.
In theory maybe this just means the top cover was put on backwards but I don’t want to open the top cover. Why? I don’t want to know what’s inside this unit because this is what was inside the older FM-500 series and it makes me a sad panda. (Spooling up turbocharger for powerful shitposting of… shit!)
Here’s the PTek FM500 series pallet overall. Not visible, or even particularly accessible, above the top of this photo, is the control logic board buried between the heatsink and the housing. Input (and output) are the tiny white cables to the right. Input’s at the top. It first goes through a buffer/driver stage, a Wilkinson 2-port power divider, through the finals, through some very unusual stripline transformers, then to a Wilkinson 2-port combiner ending with the start of the output lowpass filter, a fourth-order pi network apparatus. Seems legit, but look at those RF FET modules.
Post continues to be image-heavy so I’m going to place a break here to avoid excessive page length
