High-Linearity, 815MHz to 1000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
General Description
The MAX2029 high-linearity passive upconverter or
downconverter mixer is designed to provide +36.5dBm
IIP3, 6.7dB NF, and 6.5dB conversion loss for an 815MHz
to 1000MHz RF frequency range to support GSM/cellular
base-station transmitter or receiver applications. With a
570MHz to 900MHz LO frequency range, this particular
mixer is ideal for low-side LO injection architectures. For a
pin-to-pin-compatible mixer meant for high-side LO injec-
tion, refer to the MAX2031 data sheet.
In addition to offering excellent linearity and noise perfor-
mance, the MAX2029 also yields a high level of compo-
nent integration. This device includes a double-balanced
passive mixer core, a dual-input LO selectable switch,
and an LO buffer. On-chip baluns are also integrated to
allow for a single-ended RF input for downconversion (or
RF output for upconversion), and single-ended LO inputs.
The MAX2029 requires a nominal LO drive of 0dBm, and
supply current is guaranteed to be below 100mA.
The MAX2029 is pin compatible with the MAX2039,
MAX2041, MAX2042, MAX2044 series of 1700MHz to
2200MHz, 2000MHz to 3000MHz, and 3200MHz to
3900MHz mixers, making this family of passive upcon-
verters and downconverters ideal for applications
where a common printed-circuit board (PCB) layout is
used for multiple frequency bands.
The MAX2029 is available in a compact 20-pin thin
QFN package (5mm x 5mm) with an exposed paddle.
Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.
