Good morning all,
I'm new here and also new to millimeter microwave electronics. However, I have an urgent need for a least cost 60Ghz 250mW power amplifier and wave guide assembly for scientific tests related to Climate Change.
There is no need for signal modulation or programmable tuning via SPI comms; just full power for a typical test duration (5-30 minutes).
I'm pretty sure many of you will have some great ideas about how to proceed with such a project.
Given my limited knowledge of the subject my first thought was to start with the ADAP9007 as a pre-amp which could feed into a 3x frequency multiplier followed by a 1/4W Amp (rated output). However I know the power losses at this frequency can be substantial and also that the matching of loads is critical; and of course the circuit layout.
But, is there a more efficient approach that I'm not aware of?
Best regards and thanks in advance,
Michael
