NXP Demonstrates Energy Efficient RF Base Station Amplifier

Semiconductor firm, NXP has unveiled what it says is the world’s most efficient 3-way Doherty amplifier, enabling a new standard of energy efficient RF base stations. Based on a novel concept, the Doherty circuit performs at efficiency levels in excess of 47%, at an average power output of 48dBm, a gain of 15dB and peak to average ratio of 8dB for a multicarrier W-CDMA signal. The current design covers the W-CDMA standard for band I operation. The design is tailored towards high yield, minimum tuning, volume manufacturing.  more
