FUNCTION
NAME
Gain-Control Pin. Applying a DC voltage to GC between 0V and 2.0V adjusts the transmitter gain by
more than 40dB. GC is internally terminated to 1.35V via an 85k
resistor.
GC

Received Signal-Strength Indicator Output. The voltage on RSSI is proportional to the signal power at
LIMIN. The RSSI output sources current pulses into a 330pF (typical) external capacitor. This output is
internally terminated with 11k
, and this RC time constant sets the decay time.

Local-Oscillator Input Ground. Connect to PC board ground plane with minimal inductance.

Differential LO Inputs. In a typical application, externally terminate LO with 50

ple into LO. AC terminate
LO
directly to ground for single-ended operation, as shown in the Typical
Operating Circuit.

Baseband In-Phase Inputs. The differential voltage across these inputs forms the quadrature modulator’s
I-channel input. The signal input level is typically up to 500mVp-p centered around a 1.4V (typical) DC
bias level on

Baseband Quadrature-Phase Inputs. The differential voltage across these inputs forms the quadrature
modulator’s Q-channel input. The signal input level is typically up to 500mVp-p, centered around a 1.4V
(typical) DC bias level on

Receiver Enable Pin. When high, RXEN enables the receiver if TXEN is low. If both RXEN and TXEN are
high, the part is in standby mode; if both are low, the part is in shutdown. See the Power Management
section for details.
RXEN

Transmitter-Enable Pin. When high, TXEN enables the transmitter if RXEN is low. If both TXEN and
RXEN are high, the part is in standby mode; if both are low, the part is in shutdown. See the Power
Managementsection for details.
TXEN

Differential Outputs of the Upconverter. In a typical application, these open-collector outputs are pulled
up to V

tion for more details, including information on impedance matching these outputs to a load.

Reference Voltage Pin. VREF provides an external bias voltage for the MIXOUT and LIMIN pins. Bypass
this pin with a 0.1μF capacitor to ground. The VREF voltage is equal to V

Single-Ended Output of the Downconverter Mixer. This pin is high-impedance and must be biased to the
VREF pin through an external terminating resistor whose value depends on the interstage filter character-
