Dual, SiGe High-Linearity, 1800MHz to 2900MHz

Downconversion Mixer with LO Buffer

MX197A

General Description

Features

♦ 1800MHz to 2900MHz RF Frequency Range

The MAX19997A dual downconversion mixer is a versa-

tile, highly integrated diversity downconverter that pro-

vides high linearity and low noise figure for a multitude of

1800MHz to 2900MHz base-station applications. The

MAX19997A fully supports both low- and high-side LO

injection architectures for the 2300MHz to 2900MHz

WiMAX™, LTE, WCS, and MMDS bands, providing

8.7dB gain, +24dBm input IP3, and 10.3dB NF in the

low-side configuration, and 8.7dB gain, +24dBm input

IP3, and 10.4dB NF in the high-side configuration. High-

side LO injection architectures can be further extended

down to 1800MHz with the addition of one tuning ele-

ment (a shunt inductor) on each RF port.

♦ 1950MHz to 3400MHz LO Frequency Range

♦ 50MHz to 550MHz IF Frequency Range

♦ Supports Both Low-Side and High-Side LO

Injection

♦ 8.7dB Conversion Gain

♦ +24dBm Input IP3

♦ 10.3dB Noise Figure

♦ +11.3dBm Input 1dB Compression Point

♦ 70dBc Typical 2 x 2 Spurious Rejection at

The device integrates baluns in the RF and LO ports,

an LO buffer, two double-balanced mixers, and a pair

of differential IF output amplifiers. The MAX19997A

requires a typical LO drive of 0dBm and a supply cur-

rent guaranteed below 420mA to achieve the targeted

linearity performance.

Applications

♦ Integrated LO Buffer

♦ Integrated LO and RF Baluns for Single-Ended

The MAX19997A is available in a compact 6mm x 6mm,

36-pin thin QFN lead-free package with an exposed

pad. Electrical performance is guaranteed over the
