Active Mixer
General Description
The MAX9981 dual high-linearity mixer integrates a local
oscillator (LO) switch, LO buffer, LO splitter, and two
active mixers. On-chip baluns allow for single-ended RF
and LO inputs. The active mixers eliminate the need for
an additional IF amplifier because the mixer provides a
typical overall conversion gain of 2.1dB.
The MAX9981 active mixers are optimized to meet the
demanding requirements of GSM850, GSM900, and
CDMA850 base-station receivers. These mixers provide
exceptional linearity with an input IP3 of greater than
+27dBm. The integrated LO driver allows for a wide
range of LO drive levels from -5dBm to +5dBm. In addi-
tion, the built-in high-isolation switch enables rapid LO
selection of less than 250ns, as needed for GSM trans-
ceiver designs.
The MAX9981 is available in a 36-pin QFN package
(6mm
6mm) with an exposed paddle, and is specified
over the -40°C to +85°C extended temperature range.
