RF1, RF2
Bias pins for mixer cores. Set from 4.7V to 5.0V for operating frequency band.
RF input pins of the mixer, internally matched to 50 Ohms. RF input pins require off chip DC
blocking capacitors. See application circuit.
LO_BIAS2,
LO_BIAS1
Bias control pins for LO Amplifiers. Connect to 5V supply through 270 Ohms resistors. Refer to
application section for proper values of resistors to adjust LO amplifier current.

CHIP_EN
LON
Chip Enable. Connect to logic high for normal operation.
Negative LO output used for single-ended, differential, or dual output mode.
Positive LO output used for differential or dual outputs only. While it can drive a separate load from
LO_N, it cannot be used when LO_N is disabled.
