HF Low-Power meter based on temperature measurements

When building an ATV Transmitter at 23cm, there was a great need for a power meter for small powers

SWR bridge, Bridge 1 to 1000 Mh
It is possible to measure return loss up to 1000 Mhz, the return loss range is 0-50 to 0-40dB depending on frequency
SWR meter,I built one
Several years ago I built one to a design by G3WPO that was sold as a kit by Cirkit. It worked quite well, but it contained numerous trimmers that needed adjusting from time to time to maintain the accuracy
SWR meter for 144-1296 MHz bands
An idea of SWR-meter which I ́m going to describein this article belongs to Paul G7EYT
SWR meter
The meter automatically provides an accurate readout of SWR for any power level between 10mW and 1000W
