1 / 15 page 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.
