Function and Application Internal Equivalent Circuit
1 RFinput
1.2 RF input pin of mixer. This
mixer is designed as double
balanced type.
This pin should be externally
coupled to front stage with DC cut
capacitor.
2 GND GND
Ground pin. This pin must be
connected to the system ground.
Form the ground pattern as wide
as possible and the truck length
as short as possible to minimize
ground impedance.
5 VCC 2.7 to 3.3
Supply voltage pin.
This pin should be connected with
bypass capacitor (example: 1 000
pf) to minimize ground
impedance.
6 IFoutput as same as
V
CC voltage
through
external
inductor
IF output pin. This output is
configured with open collector of
high impedance. This pin should
be externally equipped with
matching circuit of inductor should
be selected as small resistance
and high frequency use.
3 LOinput
1.4 Input pin of local amplifier. This
amplifier is designed as differen-
tial type.
This pin should be externally
coupled to local signal source
with DC cut capacitor.
Recommendable input level is
15 to 0 dBm.
4 PS VCC or GND
Power save control pin. This pin
can control ON/OFF operation
with bias as follows;
Bias: V Operation
VPS 2.5 ON
0 to 0.5 OFF
