The MAX9982 fully integrated SiGe mixer is optimized to

meet the demanding requirements of GSM850, GSM900,

and CDMA850 base-station receivers. Each high-lineari-

ty device includes a local oscillator (LO) switch, LO dri-

ver, and active mixer. On-chip baluns are also integrated

to allow for single-ended RF and LO inputs. Since the

active mixer provides 2dB of conversion gain, the device

effectively replaces the IF amplifier stage, which typically

follows most passive mixer implementations.

The MAX9982 provides exceptional linearity with an

input IP3 of greater than +26dBm. The integrated LO

driver allows for a wide range of LO drive levels from

-5dBm to +5dBm. In addition, the built-in switch

enables rapid LO selection of less than 250ns, as need-

ed for GSM frequency-hopping applications.

The MAX9982 is available in a 20-pin QFN package

(5mm

over the -40°C to +85°C extended temperature range.
