I have also finshed first tests last week and got about same results. 60W DATV at 30V/10A. Now waiting for a bigger power supply. There is no tuning necessary. About 15 dB of gain at 2406 MHz. Maximum gain is around 2350 MHz, but only 1 -2 dB more. These pallets do have a nice PTT design. There seems to be a temperature switch on the pallet also, but I have not tested it yet. I have used a 4 mm copper plate for heat distribution and a heatsink with blower.
My pallets seem to be B-ware, but obvisiously have never been used. There are markers on the back pointing maybe to a point with lack of soldering to the copper plate. So far no problem.
I am now going to construct a PA with two of these pallets to get about 120W DATV out for my small 1,2m dish.
There was another sale on eBay, but with a pallet for 2500 - 2600 GHz. Also ordered one to see the difference.

yes a really nice and good information from you.... for the gate current power down there are analogue switches STG719 which maybe can be used for PTT with external logical level... i have not tried until now ...but it looks very interesting . I am using on the AB side about 500-600mA idle current and for the PEAK amp gate is set to 0.7V nearly like the information given in the datasheet.
Power Out in DATV reaches about 50-60W at 30V @ 8A , a bit more going upto 10A in DATV means about 75W without problem.
Tested the amp only on short time until 12.5A that gives 100W+ out ...maybe more is possible but maybe out of spec and out of DATV linearity. So i think 75W is the max for our amateur radio use.
NOTE: The DESIGN looks very narrowband so other version will maybe not work good.
THANK YOU AGAIN for your information
