Description
Ships as shown, assembled with the aluminum angle, fully built & tested.
For long operating time periods it is recommended to fix the complete assembly on a larger metal surface or heatsink. It can be fixed with 4 or 5 screws for better thermal transfer.
The R4350B PCB has a low-loss transmission line from the input N-type connector to the load and the resistor network for the sampler.
The sampler is relatively flat from 1 to 54 MHZ but workable up to 70 MHZ. It also works up to 250 MHZ by calibrating its slope.
