Description
Balanced IF Input Pin. This pin is internally DC-biased and should be
DC-blocked if connected to a device with a DC level present. For single-
ended input operation, one pin is used as an input and the other IF
input is AC coupled to ground. The input impedance is 250
in both
the balanced and single-ended modes.

GND
Same as pin 10, except complementary input.
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
Balanced LO Input Pin. This pin is internally DC-biased and should be
DC-blocked if connected to a device with a DC level present. For single-
ended input operation, one pin is used as an input and the other LO
input is AC coupled to ground. The input impedance is 50
in both the
balanced and single-ended modes.

GAIN
SELECT
Same as pin 13, except complementary input.
Supply voltage for all bias circuits and logic circuits.
When GAIN SELECT is high: the driver amplifier is switched to high
gain mode; both amplifier stages are active; the gain is maximized;
and, the entire device draws approximately 51mA. When GAIN
SELECT is low, the second stage of the PA driver is turned off and
bypassed. This results in a device current of 26mA, which is approxi-
mately a 50% current reduction. The upconverting mixer remains on in
both the high and low gain modes to prevent VCO pulling.
Ground connection. The backside of the package should be soldered to
a top side ground pad which is connected to the ground plane with mul-
tiple vias.
