PMC-Sierra M8800 Product Overview

PM8800 WiZIRD 2x2
WiMAX Zero Intermediate Frequency Radio
Device

Product Overview

The PM8800 WiZIRD 2x2 is an ultra-integrated single-chip WiMAX
Zero Intermediate Frequency (ZIF) Radio Device. It is designed for
Fixed and Mobile WiMAX applications and supports both IEEE
802.16-2004 and IEEE 802.16e-2005 standard requirements. The
PM8800 WiZIRD 2x2 has two independent radio paths (2Tx and
2Rx) and supports operation in the 2.3 - 2.9 GHz or the
3.3 - 3.8 GHz licensed bands.
The PM8800 WiZIRD 2x2 enables manufacturers of WiMAX Femto
BS, CPE, and MS User Equipment to build low-cost, high-perfor-
mance, 2x2 MIMO equipment today.
Product Highlights
Ultra-Integration
