Hi all, I now have two of these TS832's. Previously I commented that there was up to 650mW output and someone wanted to know at what frequency that was. I measured both my TS832's and added the graph to this review. Power meter: Boonton 4220 with model 7E power sensor up to 18GHz, and 40dB attenuator Aeroflex/Weinschell 24-40-34 DC to 8.5GHz. Calibrated against a 10mW reference power source at 6.0GHz. There is some ripple in my measurement setup between 5 and 6GHz, around 0.05dB. This is next to nothing and can be ignored. I don't know why one unit fails to output more and more power towards low frequencies. Possibly I inadvertently removed a small capacitor when refitting the board with an SMA connector, instead of the reverse SMA. But I have just these two units, and my area of interest is 5750MHz and up anyways, so for me it's fine. All in all I highly recommend these boards, excellent value for money. Best regards, David
