LOIN
—
—
Ground pin. This pin should be connected to
system ground with minimum inductance.
Ground pattern on the board should be formed as
wide as possible.
1.3
LO input pin. The LO buffer is designed as a
differential amplifier. Recommended input level
is -15 to 0 dBm.

—
Power supply pin. This pin should be externally
equipped with a bypass capacitor to minimize
ground impedance.

IFOUT
—
1.7
Output of single-ended push-pull IF buffer amplifier.
This is an emitter-follower output with low impedance.
This pin must be coupled to the next stage with a
blocking capacitor.
