PRODUCT OVERVIEW
The PM8801 WiZIRD 1x2 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 PM8801 WiZIRD
1x2 has independent radio paths (1Tx and 2Rx) and supports
operation in the 2.3 - 2.7 GHz or the 3.3 - 3.8 GHz licensed bands.
The PM8801 WiZIRD 1x2 enables manufacturers of WiMAX User
Equipment to build low-cost, high-performance, mobile stations and
customer premises equipment. 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 PM8801 WiZIRD 1x2 features:
-
Independent radio paths (1Tx and 2Rx) that support all Wave2 MIMO
features
- 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 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 requirements with
minimal changes.
For flexibility, the PM8801 WiZIRD 1x2 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
|
-
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.
