Efficient RF front end covers 698MHz-2.7GHz

Qorvo's latest RF Fusion solutions integrate all major transmit and receive RF functionality from the transceiver to the antenna in integrated high-band, mid-band, and low-band placements, enabling complete frequency coverage. The solutions deliver the highest levels of performance and integration to help smartphone OEMs quickly migrate to 4G LTE/TD-LTE/LTE-A and Rel-12 Carrier Aggregation- (CA-) capable devices.

Qorvo's latest RF Fusion solutions divide the front end into three compact placements – the high-band TQF6862, mid-band TQF6840 and low-band RF8136 – to optimise functional integration and ease compliance with stringent Rel-12 CA requirements. The solutions incorporate multiple filters (BAW and SAW), more than twice the previous generation, and extend performance to include full high-band (2.3-2.7GHz) coverage.

Each placement contains a multi-band PA optimised for superior performance in envelope tracking mode, advanced filters and duplexers, a routing switch, an antenna switch, and a coupler. The solutions feature premium duplexers with wafer level packaging to maximise performance and optimise form factor. This configuration provides all necessary functionality and frequency partitioning to implement full 3GPP Rel-12, 2DL or 3DL CA, a much anticipated improvement in download data rates and network spectrum efficiency.

The high-band TQF6862 covers 2.3-2.7GHz with an integrated transmit-receive switch for TD-LTE and associated filtering, followed by bandpass filters for bands 38/41 and 40 and a band 7 duplexer, in a 6.15x4.5x0.915mm package. The mid-band TQF6840 covers 1710-1980MHz with WLP duplexers integrated for bands 1, 25/2, 3 and 4, in a 7.7x5.5x0.9mm package. The low-band RF8136 covers 698-915MHz with WLP duplexers integrated for bands 26/5, 8, 20 and 12/17, as well as a band 29 receive filter, in a 6.0x7.5x1.0mm package.

Eric Creviston, President, Mobile Products Group, Qorvo, said, "Qorvo is leveraging the industry's most comprehensive product portfolio, advanced packaging technologies, and deep system-level expertise to quickly introduce highly integrated front end solutions that simplify and accelerate the implementation of multimode, multi-band 4G smartphones and tablets. These latest RF Fusion front end solutions showcase Qorvo's unique ability to combine industry-leading performance and functional density in tightly integrated form factors, helping leading OEMs to more quickly launch their next-gen flagship devices."
