FUNCTION
Ground. Connect GND to the PC board ground plane with minimal inductance.
RF Input to LNA. AC couple to this pin. At 1.9GHz, LNAIN can be easily matched to 50 ? with one
external shunt 1pF capacitor.
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.
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 160μA (typical) supply
current. If TXEN and RXEN are both at a logic low, the part is set to shutdown mode, with a
0.1μA (typical) supply current.
50 ? Local-Oscillator (LO) Input Port. AC couple to this pin.
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.
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 a 160μA (typical)
supply current. If TXEN and RXEN are both at a logic low, the part is set to shutdown mode, with
a 0.1μA (typical) supply current.
Gain-Control Input for PA 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.
Power Amplifier Driver Output. AC couple to this pin. Use external shunt inductor to V CC to match
PADROUT to 50 ? . This also provides DC bias. See the Typical Operating Characteristics for a
plot of PADROUT Impedance vs. Frequency.
PA Driver Input Grounds. Connect GND to the PC board ground plane with minimal inductance.
RF Input to Variable-Gain Power Amplifier Driver. Internally matched to 50 ? . AC couple to this
pin. This input typically provides a 2:1 VSWR at 1.9GHz. AC couple to this pin. See the Typical
Operating Characteristics for a plot of PADRIN Impedance vs. Frequency.
RF Output of Transmit Mixer (upconverter). Use an external shunt inductor to V CC as part of a
matching network to 50 ? . This also provides DC bias. AC couple to this pin. See the Typical
Operating Characteristics for a plot of TXMXOUT Impedance vs. Frequency.
Differential IF Port of Transmit (Tx) and Receive (Rx) Mixers, Inverting Side. In Rx mode, 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 in both Tx and Rx modes. Additionally, a resistor
may be placed across IF and IF to set a terminating impedance. In Tx mode, this input is internally
AC-coupled; however, AC couple to this pin externally. For single-ended operation, connect this
port to V CC and bypass with 1000pF capacitor to GND.
Differential IF Port of Tx and Rx Mixers, Noninverting Side. In Rx mode, this output is an open collec-
tor and should be pulled up to V CC with an inductor. This inductor can be part of the matching net-
work to the desired IF impedance in both Tx and Rx modes. Additionally, a resistor may be placed
across IF and IF to set a terminating impedance. In Tx mode, this input is internally AC coupled;
however, AC couple to this pin externally.
