MAX2044

19-5002; Rev 0; 10/09 SiGe, High-Linearity, 2300MHz to 4000MHz Upconversion/Downconversion Mixer with LO Buffer General Description The MAX2044 single, high-linearity upconversion/downconversion mixer provides +32.5dBm input IP3, 8.5dB noise figure, and 7.7dB conversion loss for 2300MHz to 4000MHz LTE, WiMAXK, and MMDS wireless infrastructure applications. With an ultra-wide 2600MHz to 4300MHz LO frequency range, the MAX2044 can be used in either low-side or high-side LO injection architectures for virtually all 2.5GHz and 3.5GHz applications. In addition to offering excellent linearity and noise performance, the MAX2044 also yields a high level of component integration. This device includes a doublebalanced passive mixer core, an LO buffer, and on-chip baluns that allow for single-ended RF and LO inputs. The MAX2044 requires a nominal LO drive of 0dBm, and supply current is typically 138mA at VCC = 5.0V or 121mA at VCC = 3.3V. The MAX2044 is pin similar with the MAX2029/MAX2031 650MHz to 1000MHz mixers and the MAX2039/MAX2041/ MAX2042 1700MHz to 3000MHz mixers, making this entire family of up/downconverters ideal for applications where a common PCB layout is used for multiple frequency bands. The MAX2044 is available in a compact 20-pin thin QFN (5mm x 5mm) package with an exposed pad. Electrical performance is guaranteed over the extended -40NC to +85NC temperature range. www.DataSheet4U.com Features S 2300MHz to 4000MHz RF Frequency Range S 2600MHz to 4300MHz LO Freque...
