We are using AD9375 transceiver in 2 different designs, with corresponding matching circuits in frequecy range 300-1000MHz and 3300-3800MHz. (I might add that the only difference between our two different designs is in the transceiver matching circuit)
However, the output gain of the transceiver varies drastically between 2 boards, in which in the 3300-3800 frequency range, we experience almost 8dB less gain in the output (after matching circuit).
I would appreciate if you provide us with a performance test on the working frequency range of the transceiver including associated matching circuits or any kind of additive data to see if this reduction in gain is intrinsic or we are missing something.
Thank you in advance,
