MAX9982 Datasheet | Maxim Integrated

Description The MAX9982 fully integrated Si Ge mixer is optimized to meet the demanding requirements of GSM850, GSM900, and CDMA850 base-station receivers. Each high-linearity device includes a local oscillator (LO) switch, LO driver, and active mixer. On-chip baluns are also integrated to allow for single-ended RF and LO inputs. Since the active mixer provides 2d B 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 +26d Bm. The integrated LO driver allows for a wide range of LO drive levels from -5d Bm to +5d Bm. In addition, the built-in switch enables rapid LO selection of less than 250ns, as needed for GSM frequency-hopping applications. The MAX9982 is available in a 20-pin QFN package (5mm ✕ 5mm) with an exposed paddle and is specified over the -40°C to +85°C extended temperature range. o +26.8d Bm Input IP3 o +13d Bm Input 1d B pression Point o 825MHz to 915MHz RF Frequency Range o 70MHz to 170MHz IF Frequency Range o 725MHz to 1085MHz LO Frequency Range o 2d B Conversion Gain o 12d B Noise Figure o -5d Bm to +5d Bm LO Drive o 5V Single-Supply Operation o Built-In LO Switch o ESD Protection o Internal RF and LO Baluns for Single-Ended Inputs Features Applications GSM850/GSM900 2G and 2.5G EDGE Base Station Receivers Cellular cdma One TM and cdma2000TM Base Station Receivers TDMA and Integrated Digital Enhanced Network (i DEN)TM Base Station Receivers Digital and Spread-Spectrum munication Systems Microwave Links TOP VIEW Ordering Information PART MAX9982ETP TEMP RANGE -40°C to +85°C PIN-PACKAGE 20 QFN-EP- (5mm × 5mm) - EP = exposed paddle.
