Transmit Gain vs LO Input over Temp Range
The Rx IN port is matched to 50
and has an input IP3 of +2.2 dBm
(mixer only). The down-convert mixer is buffered and has open
collectors at the pins to allow for matching to common SAW filters.
The up convert mixer has an input pin to output pin gain of 23 dB.
The output of the up-converter is designed for a power level =
+4.2 dBm (P
–1dB
).
