SiGe High-Linearity, 400MHz to 1000MHz

Downconversion Mixer with LO Buffer/Switch

General Description

Features

The MAX9984 high-linearity downconversion mixer pro-

vides 8.1dB gain, +25dBm IIP3, and 9.3dB NF for

400MHz to 1000MHz base-station receiver applica-

tions*. With an optimized 570MHz to 850MHz LO fre-

quency range, this particular mixer is ideal for low-side

LO injection receiver architectures in the cellular band.

High-side LO injection is supported by the MAX9986,

which is pin-for-pin and functionally compatible with the

MAX9984.

♦ 400MHz to 1000MHz RF Frequency Range*

♦ 325MHz to 850MHz LO Frequency Range*

(MAX9984)

♦ 960MHz to 1180MHz LO Frequency Range

(MAX9986)

♦ 50MHz to 250MHz IF Frequency Range

♦ 8.1dB Conversion Gain

♦ +25dBm Input IP3

In addition to offering excellent linearity and noise perfor-

mance, the MAX9984 also yields a high level of compo-

nent integration. This device includes a double-balanced

passive mixer core, an IF amplifier, a dual-input LO selec-

table switch, and an LO buffer. On-chip baluns are also

integrated to allow for single-ended RF and LO inputs.

The MAX9984 requires a nominal LO drive of 0dBm, and

supply current is guaranteed to be below 265mA.

♦ +13dBm Input 1dB Compression Point

♦ 9.3dB Noise Figure

♦ 71dBc 2RF-2LO Spurious Rejection at

= -10dBm

♦ Integrated LO Buffer

♦ Integrated RF and LO Baluns for Single-Ended

Inputs

♦ Low -3dBm to +3dBm LO Drive

♦ Built-In SPDT LO Switch with 54dB LO1 to LO2

Isolation and 50ns Switching Time

♦ Pin Compatible with MAX9994/MAX9996 1700MHz

to 2200MHz Mixers

♦ Functionally Compatible with MAX9993

The MAX9984/MAX9986 are pin compatible with the

MAX9994/MAX9996 1700MHz to 2200MHz mixers,

making this entire family of downconverters ideal for

applications where a common PC board layout is used

for both frequency bands. The MAX9984 is also func-

tionally compatible with the MAX9993.

The MAX9984 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.

♦ External Current-Setting Resistors Provide Option

for Operating Mixer in Reduced Power/Reduced

Performance Mode

♦ Lead-Free Package Available
