General Description

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 spuri-

ous 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 per-

formance, the MAX2051 also yields a high level of com-

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 0dBm and a supply cur-

rent 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 T

= -40°C to +85°C.
