MAX9985
Dual, SiGe, High-Linearity, 700MHz to 1000MHz
Downconversion Mixer with LO Buffer/Switch
General Description
The MAX9985 high-linearity, dual-channel downconver-
sion mixer is designed to provide approximately 6dB
gain, +28.5dBm of IIP3, and 10.5dB of noise figure (NF)
ideal for diversity receiver applications. With a 700MHz
to 1000MHz RF frequency range and a 570MHz to
865MHz LO frequency range, this mixer is ideal for low-
side LO injection architectures. In addition, the broad
frequency range makes the MAX9985 ideal for GSM
850/950, 2G/2.5G EDGE, WCDMA, cdma2000 ? , and
iDEN ? base-station applications.
The MAX9985 dual-channel downconverter achieves a
high level of component integration. The MAX9985 inte-
grates two double-balanced active mixer cores, two LO
buffers, a dual-input LO selectable switch, and a pair of
differential IF output amplifiers. In addition, integrated
on-chip baluns at the RF and LO ports allow for single-
ended RF and single-ended LO inputs. The MAX9985
requires a typical 0dBm LO drive. Supply current is
adjustable up to 400mA.
The MAX9985 is available in a 36-pin thin QFN pack-
age (6mm x 6mm) with an exposed paddle. Electrical
performance is guaranteed over the extended tempera-
ture range, from T C = -40°C to +100°C.
