Hi, I have a question with LO drive of Hittite HMC-MDB277 mixer.
My desired specs proceed as follows:
IF frequency : 13~18 GHz
LO frequency : 63 GHz
RF frequency : 76~81 GHz
Although the datasheet of the mixer says that it operates at the LO frequency of 70~90 GHz,
we are going to use LO frequency of 63 GHz.
I can expect that the conversion loss would be greater than -12 dB.
Also, I expect that my system cannot make LO input of +14 dBm. (datasheet says LO input=+14 dBm)
It would be +12~+13.5 dBm.
Is it OK to use LO drive of less than +14 dBm?
How much the degradation of conversion loss would it be?
