General Description

The MAX2039 high-linearity passive upconverter or

downconverter mixer is designed to provide 7.3dB NF

and a 7.1dB conversion loss for an RF frequency range

of 1700MHz to 2200MHz to support UMTS/WCDMA,

DCS, and PCS base-station transmitter or receiver

applications. The IIP3 is typically +34.5dBm and

+33.5dBm for downconversion and upconversion oper-

ation, respectively. With an LO frequency range of

1500MHz to 2000MHz, this particular mixer is ideal for

low-side LO injection architectures. (For a pin-to-pin-

compatible mixer meant for high-side LO injection, con-

tact the factory.)

In addition to offering excellent linearity and noise per-

formance, the MAX2039 also yields a high level of com-

ponent 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 MAX2039 requires a

nominal LO drive of 0dBm, and supply current is guar-

anteed to be below 135mA.

The MAX2039 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 MAX2039 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.

High-Linearity, 1700MHz to 2200MHz Upconversion/ Downconversion Mixer with LO Buffer/Switch High-Linearity Mixer The core of the MAX2039 is a double-balanced, highperformance passive mixer. Exceptional linearity is provided by the large LO swing from the on-chip LO buffer. Differential IF The MAX2039 mixer has an IF frequency range of DC to 350MHz. Note that these differential ports are ideal for providing enhanced IIP2 performance.
