Works well for measuring output of programmable LO chain
Note the accuracy is best over -5 to -55dBm and the error grows significantly either end of those numbers. See the AD8318 data sheet. Still usable in the 0 to -5 range. I connected the detector to a spare RF SP6T Switch port via a 30dB attenuator to measure the output of a 6GHz programmable LO for my VHF+ transverters. The PLL output at +2dBm drives a 31dB programmable attenuator, a +20dB amp, then goes through a SP6T RF switch for a typical output range of +22dBm to -9dBm over the range of 50MHz to 3400MHz, then due to my RF switch rating ouput falls off so that 5760 is down to -24dBm. The 30dBm fixed SMA attenuator puts the LO output range into the sweet spot of the AD8318 at -8dBm to -39dBm range for good accuracy through 6GHz. I correct the display for the offset. I display power measurement real time while adjusting the attenuation or frequency of the LO for each transverter, very handy. Tempted to use a second one and connect them to a bidirectional coupler for a custom RF power meter and SWR meter.

Works surprisingly well and is reasonably accurate
Use the board for 2G/3G/4G power measurement. It works well and gives consistent results
