PIN EXPLANATION
APPLICATION
does not have 50 Ω input/output impedance, but electrical characteristics such as conversion gain and
intermodulation distortion are described herein on these conditions without impedance matching. So, you should
understand that conversion gain and intermodulation distortion at input level will vary when you improve VS of RF
input with external circuit (50 Ω termination or impedance matching).
External circuits of the IC are explained in a following application note.

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 insensitive to process-condition
distribution.
This pin must be externally coupled to front stage
with capacitor for DC cut.
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.)
These pins are both base-collector of oscillator. This
oscillator is designed as differential amplifier type.
3 pin and 4 pin should be externally equipped with
tank resonator circuit in order to oscillate with
feedback loop. Also this symmetrical circuit can keep
specified performance insensitive to process-
condition distribution.
Each pin must be externally coupled to tank circuit
with capacitor for DC cut.
Supply voltage 3.0 ± 0.3 V for operation. Must be
connected bypass capacitor (e.g. 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. This pin must be externally coupled
to next stage with capacitor for DC cut.
