FUNCTION
PIN
NAME
Transmit Bias Compensation Input. Bypass with a 47pF low-inductance capacitor and 0.01μF to GND.
Do not make any other connections to this pin.
14
Transmit Mixer’s Inverting Baseband/IF Input. TXIN,
TXIN
form a high-impedance, differential input port.
See Figure 1.
13
CAP2
TXIN
Transmit Mixer’s Noninverting Baseband/IF Input. TXIN,
TXIN
form a high-impedance, differential input
port. See Figure 1.
12
TXIN
Prescaler/Oscillator Buffer Output. In divide-by-64/65 mode (DIV1 = low), the output level is 500mVp-p
into a high-impedance load. In divide-by-1 mode (DIV1 = high), this output delivers -8dBm into a 50
load. AC couple to this pin.
21
Ground connection for the Prescaler. Connect PREGND to ground for normal operation. Leave uncon-
nected to disable the prescaler and the output buffer. Connect MOD and DIV1 to ground and leave PRE-
OUT unconnected when disabling the prescaler.
20
PREOUT
PREGND
Modulus Control for the Divide-by-64/65 Prescaler. Drive MOD high for divide-by-64 mode. Drive MOD
low for divide-by-65 mode.
19
Drive VCOON with a logic high to turn on the VCO, phase shifters, VCO buffers, and prescaler. To dis-
able the prescaler, leave the PREGND pin unconnected.
17
Drive RXON and VCOON with a logic high to enable the LNA, receive mixer, and IF output buffer.
See Power Management section.
16
MOD
VCOON
RXON
Drive TXON and VCOON with a logic high to enable the transmit IF variable-gain amplifier, upconverter
mixer, and PA predriver. See Power Management section.
15
TXON
Drive DIV1 with a logic high to disable the divide-by-64/65 prescaler and connect the PREOUT pin
directly to an oscillator buffer amplifier, which outputs -8dBm into a 50
load. Drive DIV1 low for divide-
by-64/65 operation. Drive this pin low when in shutdown to minimize shutdown current.
18
DIV1
Supply-Voltage Input for Prescaler. Bypass with a 47pF low-inductance capacitor and 0.01μF to GND
(pin 20 recommended).
22
V
CC
Differential Oscillator Tank Port. See Applications Information for information on tank circuits or on using
an external oscillator.
24
TANK
Supply-Voltage Input for VCO and Phase Shifters. Bypass with a 47pF low-inductance capacitor to GND
(pin 26 recommended).
23
V
CC
Differential Oscillator Tank Port. See Applications Information for information on tank circuits or on using
an external oscillator.

Ground Connection for VCO and Phase Shifters
26
GND
