MAX2031
Description
The MAX2031 high-linearity passive upconverter or downconverter mixer is designed to provide +36d Bm IIP3, 7d B NF, and 7d B conversion loss for an 815MHz to 1000MHz RF frequency range to support GSM/cellular base-station transmitter or receiver applications. With a 960MHz to 1180MHz LO frequency range, this particular mixer is ideal for high-side LO injection architectures. For a pin-to-pin-patible mixer meant for low-side LO injection, contact the factory. In addition to offering excellent linearity and noise performance, the MAX2031 also yields a high level of ponent integration. This device includes a doublebalanced passive mixer core, a dual-input LO selectable switch, and an LO buffer. On-chip baluns are also integrated to allow for a single-ended RF input for downconversion (or RF output for upconversion), and single-ended LO inputs. The MAX2031 requires a nominal LO drive of 0d Bm, and supply current is guaranteed to be below 100m A. The MAX2031 is pin patible with the...
