Qorvo pushes small cell technology with product launches
The power duplexers and amplifiers (PAs) cover major cellular infrastructure frequency bands, including bands 1 and 3, with superior band isolation. The TQQ7101, TQQ6103 and TQQ6107 duplexers are based on Qorvo’s premium bulk acoustic wave (BAW) technology and feature low insertion loss, high isolation and industry-leading power handling.
The latest infrastructure PAs include the TQP9218, TQP9221, TQP9418, and TQP9421. The TQP9218 and TQP9221 PAs provide -48 dBc ACLR at 24.5 dB of linear output power with 20 MHz LTE signals, while the TQP9418 and TQP9421 PAs provide -48 dBc ACLR at 27 dB of linear output power with 20 MHz LTE signals.
Each of the PAs deliver 16% efficiency at the rated power levels with 30 dB gain in a 7 x 7 mm surface mount package. The PAs are fully integrated with on-chip control bias and internal temperature compensation circuits to allow for operation from a 4.5 or 5V supply and do not require linearized system techniques such as digital pre-distortion. Both the duplexers and PAs are integrated products, with a small footprint, eliminating external components. In addition, the TQP9221 PA can be utilized for Bands 4, 10, 34, and 66; the TQQ6107 duplexer is intended to be used for Band 7.
James Klein, president of Qorvo’s Infrastructure and Defense Products group, said, "These small cell products deliver the high levels of integration, transmit power, isolation, and overall performance our infrastructure customers require to improve network coverage in dense environments, such as sports stadiums, airports, train stations and large enterprise buildings. Qorvo is rapidly expanding our broad portfolio of premium products using internally sourced, differentiated technologies, and we are very pleased that key strategic customers are requesting volume shipments."
