MAX19998 Datasheet | Maxim Integrated

19-4827; Rev 0; 10/09 TION KIT EVALUA BLE AVAILA .. Si Ge, High-Linearity, 2300MHz to 4000MHz Downconversion Mixer with LO Buffer General Description The MAX19998 single, high-linearity downconversion mixer provides 8.7d B of conversion gain, +24.3d Bm input IP3, +11.3d Bm 1d B input pression point, and a noise figure of 9.7d B for 2300MHz to 4000MHz Wi MAXK, LTE, and MMDS receiver applications. With an ultra-wide LO 2600MHz to 4300MHz frequency range, the MAX19998 can be used in either low-side or high-side LO injection architectures for virtually all 2.5GHz and 3.5GHz applications. For a 2.5GHz variant tuned specifically for high-side injection, refer to the MAX19996A. In addition to offering excellent linearity and noise performance, the MAX19998 also yields a high level of ponent integration. This device includes a doublebalanced passive mixer core, an IF amplifier, and an LO buffer. On-chip baluns are also integrated to allow for single-ended RF and LO inputs. The MAX19998 requires a nominal LO drive of 0d Bm, and supply current is typically 230m A at VCC = 5.0V or 150m A at VCC = 3.3V. The MAX19998 is pin patible with the MAX19996/ MAX19996A 2000MHz to 3900MHz mixer family. The device is also pin similar with the MAX9984/MAX9986/ MAX9986A 400MHz to 1000MHz mixers and the MAX9993/MAX9994/MAX9996 1700MHz to 2200MHz mixers, making this entire family of downconverters ideal for applications where a mon PCB layout is used for multiple frequency bands. The MAX19998 is available in a pact, 5mm x 5mm, 20-pin thin QFN with an exposed pad. Electrical performance is guaranteed over the extended -40NC to +85NC temperature range.
