High-Linearity, 1700MHz to 3000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
General Description
The MAX2041 high-linearity passive upconverter or
downconverter mixer is designed to provide 7.4dB NF
and a 7.2dB conversion loss for an RF frequency range
of 1700MHz to 3000MHz to support UMTS/WCDMA,
DCS, PCS, and WiMAX base-station transmitter or
receiver applications. The IIP3 is typically +33.5dBm
for both downconversion and upconversion operation.
With an LO frequency range of 1900MHz to 3000MHz,
this particular mixer is ideal for high-side LO injection
Features
o 1700MHz to 3000MHz RF Frequency Range
o 1900MHz to 3000MHz LO Frequency Range
o 1500MHz to 2000MHz LO Frequency Range
(MAX2039)
o DC to 350MHz IF Frequency Range
o 7.2dB Conversion Loss
o +33.5dBm Input IP3
architectures. (For a pin-compatible mixer meant for
low-side LO injection, refer to the MAX2039.)
In addition to offering excellent linearity and noise perfor-
mance, the MAX2041 also yields a high level of compo-
nent integration. This device includes a double-balanced

Integrated LO Buffer
Integrated RF and LO Baluns
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 MAX2041 requires a nominal LO drive of 0dBm, and
supply current is guaranteed to be below 145mA.
The MAX2041 is pin compatible with the MAX2031
815MHz to 995MHz mixer, making this family of passive
upconverters and downconverters ideal for applications
where a common PC board layout is used for both fre-
quency bands.
The MAX2041 is available in a compact 20-pin thin
QFN package (5mm x 5mm) with an exposed paddle.
o Low -3dBm to +3dBm LO Drive
o Built-In SPDT LO Switch with 43dB LO1 to LO2
Isolation and 50ns Switching Time
o Pin Compatible with the MAX2031 815MHz to
995MHz Mixer
o External Current-Setting Resistor Provides Option
for Operating Mixer in Reduced-Power/Reduced-
Performance Mode
o Lead-Free Package Available
