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
825MHz to 915MHz, SiGe High-Linearity
Active Mixer
