General Description
The MAX2042 single, high-linearity upconversion/down conversion mixer provides +36dBm IIP3, 7.3dB noise figure, and 7.2dB conversion loss for 2000MHz to 3000MHz WCS, LTE, WiMAXK, and MMDS wireless infrastructure applications. With a wide LO frequency range of 1800MHz to 2800MHz, this particular mixer is ideal for low-side LO injection receiver and transmitter architectures. High-side LO injection is supported by the MAX2042A, which is pin pin and functionally compatible with the MAX2042.
In addition to offering excellent linearity and noise performance, the MAX2042 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 MAX2042 requires a nominal LO drive of 0dBm, and supply current is typically 138mA at VCC = +5.0V or 120mA at VCC = +3.3V.
The MAX2042 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.
