LNA Output. AC couple to this pin. This output typically provides a VSWR of better than 2:1 at frequen-
cies from 1.7GHz to 3GHz with no external matching components. At other frequencies, a matching
network may be required to match this pin to an external filter. Consult the Typical Operating
Characteristics for a plot of LNA Output Impedance vs. Frequency.
LNAOUT
27
LNA Output Ground. Connect to PC board ground plane with minimal inductance.
GND
26
Receive Mixer Input Ground. Connect to PC board ground plane with minimal inductance.
GND
25
RF Input to Receive Mixer (Downconverter). AC couple to this pin. This input typically requires a matching
network for connecting to an external filter. See the Typical Operating Characteristicsfor a plot of RXMXIN
Impedance vs. Frequency.
RXMXIN
24
IF Input of Transmit Mixer (Upconverter). AC couple to this pin. IFIN presents a high input impedance
and typically requires a matching network. See the Typical Operating Characteristics for a plot of IFIN
Impedance vs. Frequency.
IFIN
22
IF Output of Receive Mixer (Downconverter). AC couple to this pin. This output is an open collector and
should be pulled up to V
CC
with an inductor. This inductor can be part of the matching network to the
desired IF impedance. Alternatively, a resistor can be placed in parallel to this inductor to set a termi-
nating impedance. See the Typical Operating Circuitfor more information.
IFOUT
21
RF Output of Transmit Mixer (Upconverter). AC couple to this pin. Use an external shunt inductor to
V
CC
as part of a matching network to 50
. This also provides DC bias. See the Typical Operating
Characteristics for a plot of TXMXOUT Impedance vs. Frequency.
TXMXOUT
19
RF Input to Variable-Gain Power-Amplifier Driver. AC couple to this pin. Internally matched to 50
. This
input typically provides a 2:1 VSWR at 1.9GHz. See the Typical Operating Characteristics for a plot of
PADRIN Impedance vs. Frequency.
PADRIN
16
Power-Amplifier Driver Input Ground. Connect to PC board ground plane with minimal inductance.
GND
15, 17
Power-Amplifier Driver Output. AC couple to this pin. Use external shunt inductor to V
CC
to match this pin
to 50
. This also provides DC bias. See the Typical Operating Characteristics for a plot of PADROUT
Impedance vs. Frequency.
PADROUT
13
Gain-Control Input for Power-Amplifier Driver. By applying an analog control voltage between 0V and
2.15V, the gain of the PA driver can be adjusted over a 35dB range. Connect to V
CC
for maximum gain.
GC
11
Logic-Level Enable for Transmitter Circuitry. A logic high turns on the transmitter. When TXEN and
RXEN are both at a logic high, the part is placed in standby mode, with 160μA (typical) supply current.
If TXEN and RXEN are both at a logic low, the part is set to shutdown mode, with 0.1μA (typical) supply
current.
TXEN

50
Inverting Local-Oscillator Input Port. For single-ended operation connect
LO
directly to GND. If a
differential LO signal is available, AC couple the inverted LO signal to this pin.
LO

50
Local-Oscillator (LO) Input Port. AC couple to this pin.
LO
7
Logic-Level Enable for Receiver Circuitry. A logic high turns on the receiver. When TXEN and RXEN are
both at a logic high, the part is placed in standby mode, with a supply current of 160μA (typical). If
TXEN and RXEN are both at a logic low, the part is set to shutdown mode, with a supply current of
0.1μA (typical).
RXEN
6
Supply Voltage (2.7V to 5.5V). Bypass V
CC
to GND at each pin with a 47pF capacitor as close to each
pin as possible.

RF Input to the LNA. AC couple to this pin. At 1.9GHz, LNAIN can be easily matched to 50
with one
external shunt 1pF capacitor.
LNAIN

PIN
Ground. Connect to PC board ground plane with minimal inductance.
