The wireless industry today is challenged with producing base stations to multiple standards such as CDMA2000, WCDMA, TD-SCDMA, and ODFM/WiMAX. These new wireless standards put an ever-increasing demand on the multi-carrier power amplifier (MCPA) with higher peak-to-average power ratios. At the same time, the market is placing unprecedented pressure on the industry to lower capital cost, shrink size and increase power efficiency. Currently analog MCPAs represent as much as 40% of the capital cost of a base station and occupy a similar percentage of rack space and consume a major portion of power delivered to the site.
A New Design Approach for MCPAs
PulseWave RF has achieved an industry milestone by moving components of a BTS transmitter from the analog to the digital world resulting in a dramatic cost and size reduction and an increase in efficiency for MCPAs.
The Class M Power Module is a digital MCPA module that simultaneously sets new industry benchmarks for cost, size, and efficiency. MCPAs implemented with Class M Power modules cost 50% less than analog MCPAs. The module is a mere 2.25" x 2.75" (60 mm x 70 mm) producing 100 watts of peak power at 25% efficiency. Class M Power delivers on all three fronts - cost, size, and efficiency. |
