The MAX2051 is a high-linearity, up/downconversion mixer that provides +35dBm input IP3, 7.8dB noise figure (NF), and 7.4dB conversion loss for 850MHz to 1550MHz wireless infrastructure and multicarrier cable head-end downstream video, video-on-demand (VOD), and cable modem termination systems (CMTS) applications.
The MAX2051 provides high linearity and low noise performance for broadband wireless and cable‑head‑end applications. It integrates RF and LO baluns, a low‑drive LO buffer, and supports single‑ended RF and LO inputs. Typical specifications include +35 dBm input IP3, 7.8 dB noise figure, and 7.4 dB conversion loss.
The device operates from –40 °C to +85 °C, is supplied at 4.75‑5.5 V, and draws up to 130 mA. It is offered in a 5 mm × 5 mm, 20‑pin thin QFN package with an exposed pad for thermal management. The mixer supports RF frequencies from 850 MHz to 1550 MHz, LO frequencies from 1200 MHz to 2250 MHz, and IF frequencies from 50 MHz to 1000 MHz.
