Function and Explanation

1.4

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 3

board should be formed as wide

as possible. Track Length should

be kept as short as possible to

minimize ground impedance.

2.3

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.

Power save control pin. Bias
