MAX19996A Datasheet | Maxim Integrated

19-4402; Rev 1; 5/09 .. Si Ge, High-Linearity, 2000MHz to 3900MHz Downconversion Mixer with LO Buffer General Description The MAX19996A single, high-linearity downconversion mixer provides 8.7d B conversion gain, +24.5d Bm IIP3, and 9.8d B noise figure for 2000MHz to 3900MHz WCS, LTE, Wi MAX™, and MMDS wireless infrastructure applications. With an ultra-wide LO frequency range of 2100MHz to 4000MHz, the MAX19996A 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 low-side injection, refer to the MAX19996 data sheet. In addition to offering excellent linearity and noise performance, the MAX19996A also yields a high level of ponent integration. This device includes a double-balanced 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 MAX19996A 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 MAX19996A is pin patible with the MAX19996 2000MHz to 3000MHz mixer. 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 MAX19996A is available in a pact 5mm x 5mm, 20-pin thin QFN with an exposed pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.
