This pin is RF input for mixer
designed as double balance type.
This circuit contributes to suppress
spurious signal with minimum LO
and bias power consumption.
Also this symmetrical circuit can
keep specified performance insensi-
tive to process-condition distribution.
This pin is ground of IC.
Must be connected to the system
ground with minimum inductance.
Ground pattern on the board should
be formed as wide as possible.
(Track length should be kept as
short as possible.)
This pin is LO input for local buffer
designed as differential amplifier.
Recommendable input level is –15
to –0 dBm. Also this symmetrical
circuit can keep specified
performance insensitive to process-
condition distribution.
This pin is for power-save function.
This pin can control ON/OFF
operation with bias as follows;
Rise time/fall time using this pin are
approximately 10 s.
Supply voltage 3.0 0.3 V for
operation. Must be connected
bypass capacitor. (example: 1 000
pF) to minimize ground impedance.
This pin is output from IF buffer
amplifier designed as single-ended
push-pull type. This pin is assigned
for emitter follower output with low-
impedance. In the case of
connecting to high-impedance
stage, please attach external
matching circuit.
