The MAX2042A single, high-linearity upconversion/downconversion mixer provides up to +33dBm input IP3, 7.25dB noise figure, and 7.2dB conversion loss for 1600MHz to 3900MHz GSM/EDGE, CDMA, TD-SCDMA, WCDMA, LTE, TD-LTE, WiMAX™, and MMDS wireless infrastructure applications. With an ultra-wide 1300MHz to 4000MHz LO frequency range, the IC can be used in either low-side or high-side LO injection architectures for virtually all 1.7GHz to 3.5GHz applications (for a 2.5GHz variant tuned specifically for low-side LO injection, refer to the MAX2042). In addition to offering excellent linearity and noise performance, the IC also yields a high level of component integration. This device includes a double-balanced passive mixer core, an LO buffer, and on-chip baluns that allow for single-ended RF and LO inputs. The IC requires a nominal LO drive of 0dBm, and supply current is typically 140mA at VCC = 5.0V or 122mA at VCC = 3.3V. The MAX2042A is pin compatible with the MAX2042 2000MHz to 3000MHz mixer. The MAX2042A is also pin similar with the MAX2029/MAX2031/MAX2033 650MHz to 1550MHz mixers, the MAX2039/MAX2041 1700MHz to 3000MHz mixers, and the MAX2044 2300MHz to 4000MHz mixer, making the entire family of upconverters/downconverters ideal for applications where a common PCB layout is used for multiple frequency bands. The MAX2042A is available in a compact, 20-pin TQFN package (5mm x 5mm) with an exposed pad. Electrical performance is guaranteed over the extended TC = -40°C to +85°C temperature range.
