GND

Ground Connections. These pins must be connected to RF and dc ground.

2

IF_IP

Positive IF In Phase Input. This pin is dc-coupled. When operation to dc is not

required, block this pin externally using a series capacitor with a value chosen

to pass the necessary frequency range. For operation to dc, this pin must not

source or sink more than 3 mA of current or device malfunction and device

failure may result.

3

IF_IN

Negative IF In Phase Input. This pin is dc-coupled. When operation to dc is not

required, block this pin externally using a series capacitor with a value chosen

to pass the necessary frequency range. For operation to dc, this pin must not

source or sink more than 3 mA of current or device malfunction and device

failure may result.

4

IF_QN

Negative IF Quadrature Input. This pin is dc-coupled. When operation to dc is

not required, block this pin externally using a series capacitor with a value chosen

to pass the necessary frequency range. For operation to dc, this pin must not

source or sink more than 3 mA of current or device malfunction and device failure

may result.

5

IF_QP

Positive IF Quadrature Input. This pin is dc-coupled. When operation to dc is

not required, block this pin externally using a series capacitor with a value

chosen to pass the necessary frequency range. For operation to dc, this pin

must not source or sink more than 3 mA of current or device malfunction and

device failure may result.

7

VGA_VG12

Gate Control for the First and Second Stage Variable Gain Amplifier. See Figure 86

for the recommended external components.

9

VGA_VD12

Drain Voltage for the First and Second Stage Variable Gain Amplifier. See Figure 86

for recommended external components.

10

ENV_DET

Envelope Detector. See Figure 86 for the recommended external components.
