RF Power Products Reduce Operating Costs for Multi-Carrier Wireless Base Station Amplifiers
Freescale Semiconductor introduces three new RF LDMOS power transistors that deliver ultra high output levels required for Doherty-type, multi-carrier power amplifiers (MCPAs) used in wireless base station transceivers. Freescale's MRF8S18260H/S, MRF8P18265H/S, and MRF8S19260H/S products are the newest members of Freescale's High Voltage Eighth Generation (HV8) family of RF power amplifiers. They deliver the highest output levels in Freescale's RF LDMOS power transistor portfolio for the 1800 and 1900 MHz bands. MCPAs allow wireless service providers to increase the coverage and capacity of their existing base stations without dedicating one amplifier per carrier, as was often required in the past. MCPA technology allows a single amplifier to handle multiple carriers, thereby decreasing the size and component count of end products. In addition, Doherty configurations make the power amplifier more energy efficient, lowering the base station's annual operating costs.
