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
Integration of key transmit and receive path components dramat-
ically reduces the cost of materials and manufacturing, at the 
same time improving system reliability. 
The PM8800 WiZIRD 2x2 features:
Two independent radio paths (2Tx and 2Rx) supporting all Wave 
2 MIMO features and enabling the radio path for uplink MIMO 
enhancements
Zero-IF architecture removes the cost associated with external 
SAW filters
Integrated DCXO supports AFC with no additional components, 
except for a low-cost 40 MHz crystal 
Integrated synthesizer loop filter improves noise immunity and 
reduces board space requirements
40 MHz reference is available for use by the Baseband MAC 
Processor
Diagnostic loopback circuits for radio calibration and baseband 
diagnostics
Integrated DAC/ADCs for digital I/Q designs allow Baseband 
MAC Processors to scale with Moore's Law without being 
burdened with analog circuits
Integrated transmit baluns, digital temperature monitor, and Rx 
DC offset capability
Design Flexibility
Design flexibility is essential for equipment manufacturers, 
allowing them to react and adapt to changes in market require-
ments with minimal changes. 
For flexibility, the PM8800 WiZIRD 2x2 includes:
Multi-band support for operation in the 2.3 - 2.9 GHz or the 
3.3 - 3.8 GHz licensed bands, enabling system designs that are 
suitable for use across multiple geographies
The choice of selecting an analog or digital I/Q interface to an 
external Baseband MAC Processor. This lets designers use the 
best-in-class Baseband MAC Processor or ASIC available both 
now and in the future. The digital I/Q interface is compliant 
with JEDEC JESD207, Radio Front End - Baseband Digital Parallel 
Interface standard.
Configurable channel bandwidths of 3.5 MHz, 5 MHz, 7 MHz, 
8.75 MHz, 10 MHz, 14 MHz, and 20 MHz 
Programmable transmitter gain control for mobile applications
Reliable Performance
PMC-Sierra has supplied and supported high performance 
semiconductor solutions to the communications industry for over 
a decade. The same performance philosophy applies to our 
WiMAX products.
