FUNCTION
RF Input. This input is internally matched to 50 ? and is DC shorted to ground.
RF Balun Center Tap. Connect bypass capacitors from this pin to ground.
Ground
Bias control for the mixer. Connect a 249 ? resistor from this pin to ground to set the bias
current for the mixer.
Power-Supply Connections. Connect a 0.1μF bypass capacitor from each V CC pin to ground.
Local Oscillator Select. Set this pin to logic HIGH to select LO1; set to logic LOW to select
LO2.
Local Oscillator Input 1. This input is internally matched to 50 ? and is DC shorted to ground
when selected. Requires a DC-blocking capacitor.
Local Oscillator Input 2. This input is internally matched to 50 ? and is DC shorted to ground
when selected.
Differential IF Output. Connect 560nH pullup inductors and 137 ? pullup resistors from each
of these pins to V CC for a 70MHz to 120MHz IF range.

Detailed Description
The MAX9982 downconverter mixer is designed for
GSM and CDMA base station receivers with an RF fre-
quency between 825MHz and 915MHz. It implements
an active mixer that provides 2dB of overall conversion
gain to the receive path, removing the need for an addi-
tional IF amplifier. The mixer has excellent input IP3
measuring +26.8dBm. The device also features inte-
grated RF and LO baluns that allow the mixers to be
driven with single-ended signals.
RF Inputs
The MAX9982 has one input (RF) that is internally
matched to 50 ? requiring no external matching compo-
nents. A 33pF DC-blocking capacitor is required at the
input since the input is internally DC shorted to ground
through a balun. The input frequency range is 825MHz
to 915MHz.
LO Inputs
The mixer can be used for either high-side or low-side
injection applications with an LO frequency range of
8
