825MHz to 915MHz, Dual SiGe High-Linearity  
Active Mixer  
General Description  
Features  
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.  
+27.3dBm Input IP3  
+13.6dBm Input 1dB Compression Point  
825MHz to 915MHz RF Frequency Range  
70MHz to 170MHz IF Frequency Range  
725MHz to 1085MHz LO Frequency Range  
2.1dB Conversion Gain  
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.

Built-In LO Switch with 52dB LO1 to LO2 Isolation  
ESD Protection  
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.
