RF Micro Devices Inc.'s RF724x power amplifiers
support ultra-high peak efficiency of 48-51 percent and is comprised of five
PAs covering WCDMA bands 1, 2, 4, 5 and 8, addressing common 3G/4G frequency
bands and band combinations. All RF724x power amplifiers are packaged in a 3x3
mm footprint, improving smartphone platform flexibility and ease of
implementation. RFMD's RF724x power amplifiers also feature an integrated high
directivity coupler, standard 2-bit GPIO control logic and low insertion phase
shift between bias states.
When combined with one of
RFMD's companion dc-dc converters or with chipsets featuring on-chip dc-dc
converter functionality, RFMD's RF724x power amplifiers can deliver DG.09
performance as low as 13 mA - directly translating into 3G talk time.
