19-4582; Rev 0; 4/09 Si Ge, High-Linearity, 850MHz to 1550MHz Up/Downconversion Mixer with LO Buffer General Description The MAX2051 high-linearity, up/downconversion mixer provides +35d Bm input IP3, 7.8d B noise figure (NF), and 7.4d B 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 also provides excellent suppression of spurious intermodulation products (> 77d Bc at an RF level of -14d Bm), 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 highside 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 ponent 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 0d Bm and a supply current guaranteed to below 130m A. The MAX2051 is available in a pact 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.
