Qorvo has announced a new family of power amplifiers (PAs) for small cell base station applications to improve connectivity, expand capacity and minimize disruptions on LTE/LTE-Advanced networks.
This new family of small cell PAs targets distributed antenna systems, or DAS. Systems using these PAs can eliminate the need for linearization or digital pre-distortion (DPD) correction, reducing system complexity. Their eight new PAs cover 3GPP bands between 1.8-2.4 GHz and are pin-for-pin compatible.
Multi-mode, multi-band small cell base stations pose significant RF challenges in terms of size, power added efficiency, and co-existence between WLAN and cellular frequency bands. Qorvo has worked closely with customers to address these RF challenges to create a portfolio of PAs, low noise amplifiers (LNAs), filters and duplexers to enable carrier aggregation in small cell base stations.
While mobile operators continue to deploy outdoor macrocell sites to increase capacity, the wireless industry is transitioning to in-building wireless solutions. LTE/LTE-Advanced drives the need to extend wireless signal coverage indoors for corporate offices, hospitals, shopping malls, and other enterprise clients. Distributed Antenna Systems (DAS) and carrier-grade OEM small cell solutions like Ericsson Radio Dot, Huawei LampSite, Nokia Flexi Zone and ZTE's Qcell are key technologies that address the ever growing in-building wireless coverage/capacity problem.
Qorvo's multi-stage PAs integrate matching in a low-cost surface mount package to allow for compact system design. With superior linear performance at -47dBc ACLR using a 20 MHz LTE signal, the TQP92xx product family provides 24 dBm average linear power, and the TQP94xx family provides 27 dBm average linear power. These amplifier are in production and available now.
Qorvo is showcasing these products in their Booth at IMS 2016 in San Francisco from May 24-26 at the Moscone Center.
