Function and Explanation
Equivalent Circuit
1
IFinput
1.3
This pin is IF input to double balanced
mixer (DBM). The input is designed as
high impedance. The circuit contri-
butes to suppress spurious signal.
Also this symmetrical circuit can keep
specified performance insensitive to
process-condition distribution. For
above reason, double balanced mixer
is adopted.
2GND
0
GND pin. Ground pattern on the board
should be formed as wide as possible.
Track Length should be kept as short
as possible to minimize ground
impedance.
3
LOinput
2.4
Local input pin. Recommendable input
level is
−10 to 0 dBm.
5VCC
2.7 to 5.5
Supply voltage pin.
6
RFoutput Same bias
as VCC
through
external
inductor
This pin is RF output from DBM. This
pin is designed as open collector. Due
to the high impedance output, this pin
should be externally equipped with LC
matching circuit to next stage.
