Introduction

The MAX2051 high-linearity, up/downconversion mixer provides +35 dBm 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 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 highside LO injection applications over an IF frequency range of 50MHz to 1000MHz.
