Amp Aims At High Efficiency

Nujira and RF Micro Devices (RFMD) have teamed on what they feel is the world's most efficient broadband power amplifier. Based on gallium nitride (GaN) technology, the RFG1M family of amplifiers from RFMD use Nujira's Coolteq.h envelope tracking power modulators to achieve better than 50-percent efficiency across a bandwidth of 728 to 960 MHz. The design is based on RFMD's model RFG1M09180 180-W GaN transistor. The two companies hope to combine their resources to cover the cellular frequency range from 700 to 2600 MHz with just three amplifiers in the near future.
