PM8800 WiZIRD 2x2

WiMAX Zero Intermediate Frequency Radio Device

Released

Product Brief

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 - 2.7 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-performance, 2x2

MIMO equipment today.

For flexibility, the PM8800 WiZIRD 2x2 includes:

• Multi-band support for operation in the 2.3 - 2.7 GHz or the 3.3

- 3.8 GHz licensed bands, enabling system designs that are suitable

for use across multiple geographies

PRODUCT HIGHLIGHTS

ULTRA-INTEGRATION

Integration of key transmit and receive path components dramatically

reduces the cost of materials and manufacturing, at the same time

improving system reliability.

• 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.

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

• Configurable channel bandwidths of 3.5 MHz, 5 MHz, 7 MHz,

8.75 MHz, 10 MHz, 14 MHz, and 20 MHz

• Zero-IF architecture removes the cost associated with external SAW

filters

• Programmable transmitter gain control for mobile applications

• Integrated DCXO supports AFC with no additional components,

RELIABLE PERFORMANCE

except for a low-cost 40 MHz crystal

PMC-Sierra has supplied and supported high performance semicon-

ductor solutions to the communications industry for over a decade.

The same performance philosophy applies to our WiMAX products.

• Integrated synthesizer loop filter improves noise immunity and

reduces board space requirements

• 40 MHz reference is available for use by the Baseband MAC

Transmit Path

Processor

• EVM (measured after integrated balun): -36 dB @Pout = 0 dBm

(2.5 GHz), -34 dB @Pout = 0 dBm (3.5 GHz)

• Diagnostic loopback circuits for radio calibration and baseband

diagnostics

• Tx power control range: 70 dB (1 dB steps)

• -140 dBm/Hz noise floor

Receive Path

• Integrated DAC/ADCs for digital I/Q designs allow Baseband MAC

Processors to scale with Moore's Law without being burdened with

analog circuits

• EVM: -36 dB (2.5 GHz), -34 dB (3.5 GHz)

• Integrated transmit baluns, digital temperature monitor, and Rx DC

offset capability

• RFIC noise figure: 2.9 dB (2.5 GHz), 3.3 dB (3.5 GHz)

• Rx gain control: 93 dB range (1.5 dB steps), 106 dB max gain

• Adjacent channel rejection: 26 dB (64 QAM)

• Alternate channel rejection: 34 dB (64 QAM)

DESIGN FLEXIBILITY

Design flexibility is essential for equipment manufacturers, allowing

them to react and adapt to changes in market requirements with

minimal changes.
