Can you try attaching a coax tail direct from the PA section to a power meter?

-- The unit takes in Rx 0,5A and in TX 0,58A.
-- I measured the output on the module with the 150Mhz scope, and it shows 2,5Vpp.
I also tested all capacitors and diodes and so on. There is no fault.

I gather that the Mitsubishi PA modules available on the open market are quite often fakes!
