Mw-meter 60dB dynamic range from 0-500 MHz using the AD8307
Photograph of finished unit:
Features: This unit works very well with the couplers described on another page. The enormous dynamic range makes it possible to use it as an absolute power readout in any HF-VHF-UHF system. Return loss measurement is no problem because of the high dynamic range. For tuning purposes it has also a relative readout.
