SiGe, High-Linearity, 2300MHz to 4000MHz

Downconversion Mixer with LO Buffer

General Description

Features

S 2300MHz to 4000MHz RF Frequency Range

The MAX19998 single, high-linearity downconversion

mixer provides 8.7dB of conversion gain, +24.3dBm

input IP3, +11.3dBm 1dB input compression point,

and a noise figure of 9.7dB for 2300MHz to 4000MHz

WiMAXK, LTE, and MMDS receiver applications. With

an ultra-wide LO 2600MHz to 4300MHz frequency

range, the MAX19998 can be used in either low-side

or high-side LO injection architectures for virtually all

2.5GHz and 3.5GHz applications. For a 2.5GHz vari-

ant tuned specifically for high-side injection, refer to the

MAX19996A.

In addition to offering excellent linearity and noise per-

formance, the MAX19998 also yields a high level of

component integration. This device includes a double-

balanced passive mixer core, an IF amplifier, and an LO

buffer. On-chip baluns are also integrated to allow for

single-ended RF and LO inputs. The MAX19998 requires

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

S Pin Similar with the MAX9984/MAX9986/

MAX9986A Series of 400MHz to 1000MHz Mixers

and the MAX9993/MAX9994/MAX9996 Series of

1700MHz to 2200MHz Mixers

The MAX19998 is pin compatible with the MAX19996/

MAX19996A 2000MHz to 3900MHz mixer family. The

device is also pin similar with the MAX9984/MAX9986/

MAX9986A 400MHz to 1000MHz mixers and the

MAX9993/MAX9994/MAX9996 1700MHz to 2200MHz

mixers, making this entire family of downconverters ideal

for applications where a common PCB layout is used for

multiple frequency bands.

S Single 5.0V or 3.3V Supply

S External Current-Setting Resistors Provide Option

for Operating Device in Reduced-Power/Reduced-

Performance Mode

The MAX19998 is available in a compact, 5mm x 5mm,

20-pin thin QFN with an exposed pad. Electrical perfor-

mance is guaranteed over the extended -40NC to +85NC

temperature range.
