Misuratore di guadagno d'antenna
Il guadagno G puo' essere ottenuto comparando il valore della max.densita' di potenza in una particolare direzione del DUT con l'analoga densita' di potenza di una antenna di riferimento
PCB Vswr bridge
When building HF/VHF equipment it is often required to add a VSWR sensing circuit into the rig
QRP Wattmeter
The PIC16C71 microprocessor offers a four input Analogue to Digital converter, which I could use to read the voltages from the sensor and enough interface pins to drive an LCD display
