General Description

Features

Functional Diagram

No External Components Required

LO / RF Isolation: 30 dB

Input IP3: +21 dBm

Ultra Small SOT26 Package

Typical Applications

The HMC285 / HMC285E is ideal for:

• PCS

• W-CDMA

• 2.4 GHz ISM

• MMDS

The HMC285 & HMC285E are ultra miniature single

balanced mixers in 6 lead plastic surface mount SOT26

packages. This passive MMIC mixer is constructed of

GaAs Schottky diodes and a novel planar transformer

balun on the chip. The RF port is balanced via the

MMIC balun while the LO port is connected directly

to the diodes. The consistent MMIC performance will

improve system operation without the need for exter-

nal components. The SOT26 package is the small-

est footprint available for a complete single-balanced

mixer, 0.118” x 0.118” (3 x 3 mm).
