HMC285

v00.0700

General Description

Features

Functional Diagram

No External Components Required

LO / RF Isolation: 30 dB

Input IP3: +20 dBm

Ultra Small SOT26 Package

Typical Applications

The HMC285 is ideal for:

• PCS

• W-CDMA

• 2.4 GHz ISM

• MMDS

The HMC285 is an ultra miniature single bal-

anced mixer in an 6 lead plastic surface mount

SOT26 package. This passive MMIC mixer is con-

structed 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 con-

sistent MMIC performance will improve system

operation without the need for external compo-

nents. The SOT26 package is the smallest foot-

print available for a complete single-balanced

mixer, 0.118” x 0.118” (3.0mm x 3.0mm).
