However, I can’t use my wattmeter while using the coupler as a sampler. Thus this project was born to build a high quality “lab grade” RF Sampler. Following the…

    If you’re going to be building and testing amplifiers, you’ll need a high power dummy load or attenuator. The latter basically being the former with a way to tap off a highly attenuated signal, to feed a Spectrum Analyzer, for example. These dummy load attenuators can get very pricey. Here’s the gold standard, the Bird 8329-300 High-Power…
