The MAX2051 high-linearity, up/downconversion mixer 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 down-stream video, video-on-demand (VOD), and cable modem termination systems (CMTS) applications. The MAX2051 also provides excellent suppression of spurious intermodulation products (> 77dBc at an RF level of -14dBm), making it an ideal downconverter for DOCSIS® 3.0 and Euro DOCSIS cable head-end systems. With an LO circuit tuned to support frequencies ranging from 1200MHz to 2250MHz, the MAX2051 is ideal for high-side LO injection applications over an IF frequency range of 50MHz to 1000MHz.
In addition to offering excellent linearity and noise performance, the MAX2051 also yields a high level of component
integration. The device integrates baluns in the RF and LO ports, which allow for a single-ended RF input and a single-ended LO input. The MAX2051 requires a typical LO drive of 0dBm and a supply current guaranteed to below 130mA.
The MAX2051 is available in a compact 5mm x 5mm, 20-pin thin QFN package with an exposed pad. Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +85°C.
