RF filters are really just a handful of strategically placed inductors and capacitors. Yes, you can make a 1 GHz filter out of through-hole components ... an order from a board house to verify ...

So far he’s demonstrated it with a bandpass filter and a dummy load, but he suggests it should also be suitable for amplifiers using RF gain blocks. Best of all, the board is open source ...

VSWR can also be expressed in terms of decibels (dB). There are several mounting styles for RF low pass filters. Surface mount technology (SMT) adds components to a printed circuit board (PCB) by ...
