This pin is IF input to double bal-
anced mixer (DBM). The input is
designed as high impedance.
The circuit contributes to sup-
press spurious signal. Also this
symmetrical circuit can keep
specified performance insensitive
to process-condition distribution.
For above reason, double bal-
anced 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 imped-
ance output, this pin should be
externally equipped with LC
matching circuit to next stage.
