Note
This pin is IF input to double
balanced mixer (DBM). The input
is designed as high impedance.
The circuit contributes 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.
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.
Local input pin.
Recommendable input level is
–10 to 0 dBm.
Supply voltage pin.
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.
Power save control pin.
Bias controls operation as follows.
