PMC-Sierra Expands WiMAX Silicon for Global Spectrum Coverage

PMC-Sierra has added four new multi-band devices to its WiZIRD family of highly integrated WiMAX RF IC solutions for broadband wireless subscriber equipment.


The new silicon enables equipment suppliers to leverage a single radio design to provide Customer Premises Equipment (CPE) and Network Interface Cards (NICs) for all popular broadband wireless radio bands (450-928 MHz, 2.3-2.7 GHz, 2.7-2.9 GHz, 3.3-3.8 GHz and 4.9-5.95 GHz) for worldwide WiMAX deployments.


PMC-Sierra said the lack of a cohesive global spectrum policy has added complexity for system vendors and carriers. For example, the Government of India recently announced its policy and guidelines for a WiMAX spectrum, establishing plans for an auction in the 2.3 and 2.5 GHz bands for broadband wireless data services and provisions for future auctions of the 700 MHz and 3.3-3.6 GHz bands when available. In addition, the existing 2.7-2.9GHz spectrum is being selected for WiMAX services. The WiZIRD devices offer multi-band support, enabling WiMAX equipment to be developed for global markets.


The new products include:

  • PM8850 - Two transmit and two receive branches (2Tx/2Rx) with multi-band support for 2.3-2.9 GHz, 3.3-3.8 GHz and 4.9-5.95 GHz..


  • PM8851 - One transmit and two receive branches (1Tx/2Rx), with multi-band support for 2.3-2.9 GHz, 3.3-3.8 GHz and 4.9-5.95 GHz.


  • PM8870 - 2Tx/2Rx with multi-band support for 2.3-2.9 GHz, 3.3-3.8 GHz and 450-928 MHz .


  • PM8871 - 1Tx/2Rx with multi-band support for 2.3-2.9 GHz, 3.3-3.8 GHz and 450-928 MHz.


PMC-Sierra's WiZIRD RF chips integrate ZIF RF transceiver, analog and digital converters, and an industry-standard JEDEC JESD207 compliant baseband digital interface. The devices use a harmonic canceling technique to achieve extremely linear output at high power levels and deliver up to 64QAM modulation for Tx paths at 0dBm output power level with an EVM rating that addresses a complete spectrum of WiMAX solutions, from base station applications to mobile subscriber solutions.http://www.pmc-sierra.com
