CDMA amplifier solution offers low cost and high performance

26 March 2003 Telecoms, Datacoms, Wireless, IoT

Philips Semiconductors has introduced a high­performance amplifier solution for code division multiple access (CDMA) cellular telephone basestations. The line­up enables designers to create a 60 W RF power amplifier with reduced component count, smaller package size and increased performance, said to be at a better price than other options available.

As users of mobile services demand higher and higher data rates, particularly for multimedia data services, a new generation of basestation amplifiers with higher peak-to-average power ratios is required. Philips Semiconductors' LDMOS (laterally diffused-MOS) technology meets this requirement and integrated modules help to reduce time-to-market and cost.

"The high level of integration in the driver stages, combined with the high power per package provided by the final stages, produces unprecedented levels of performance and a very high power output," said Rick Dumont, international product marketing manager for cellular basestations at Philips Semiconductors. "Alternative solutions require a much higher component count, are twice the size and significantly more expensive. By implementing this solution, cellular basestation developers can quickly and cheaply build high-performance RF amplifiers for CDMA standards.''

The initial product specification includes the BGF802-20 CDMA800 power module and the BLF0810-180 LDMOS transistor. An amplifier reference design using a single BGF802-20 and two BLF0810-180 transistors is also available. The BGF802-20 is the latest of a series of LDMOS linear power modules for basestations, all sharing the same dimensions, designed to be implemented as a power module and final transistor. The series supports data services such as CDMA2000 and EDGE. For CDMA, a 1900 MHz module is also offered and for the EDGE standard, modules for 800/900/1800/1900 MHz are available, together with matching final stage transistors.

The BLF0810-180 is an LDMOS transistor and provides high power gain with easy power control and superior ruggedness. For lower power requirements, a 90 W version (BLF0810-90) is also available in the same standard package.
