All linearity and NF performances are intended at maximum LO amplitude (LO_A[1:0]=[11]), tuning capacitors (CAP[2:0])

programmed according to the selected frequency, mixer bias (MIX[3:0]) set to maximize performance and the device

operated in high current mode. The performances of conversion gain, NF and linearity are intended at the SMA connectors

of a typical application board.

The IF frequency range supported by the IF Amplifier is from 70 to 400 MHz. The exact IF frequency range supported for a

specific RF frequency can be calculated as FIF = ABS(FLO-FRF) where FLO is inside the specified LO frequency range.

Guaranteed by design and characterization

RFin = 0 dBm/tone, RF tone spacing = 5 MHz
