Rainbow Electronics MAX2051 - Manual

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
C = -40°C to +85°C.
