Function and Explanation

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.

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.
