Function and Explanation
Equivalent Circuit
1.2
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.
