Typical Applications

The HMC277MS8 / HMC277MS8E is ideal for:

• Cellular / 3G Infrastructure

• Basestations & Repeaters

• GSM, CDMA & WCDMA

• Subscribers & Portables

General Description

The HMC277MS8 & HMC277MS8E are general

purpose single balanced mixers in 8 lead plastic

surface mount Mini Small Outline Packages (MSOP).

This passive MMIC mixer is constructed of GaAs

Schottky diodes and a novel planar transformer balun

on the chip. The HMC277MS8(E) requires no external

matching components, and is ideal for upconverter

and downconverter applications. The RF port is

balanced via the MMIC balun while the LO port is

connected directly to the diodes. This product is pin

for pin compatible with the HMC272MS8(E) which

operates from 1.7 to 3.0 GHz.
