At the 2017 Mobile World Congress in Barcelona, Qorvo's mobile products business made three product announcements:
New RF front-ends for mid-tier phones
Qorvo has added two RF front-ends (RFFE) to its RF Flex™ family, describing them as fifth-generation front-end modules (FEM) that meet the challenging requirements of carrier aggregation (CA) — intra-band uplink CA as well as three-carrier inter-band downlink CA — and support all major 4G baseband processors:
The QM56022 features low-, medium- and high-band power amplifiers (PA) and band-select switches in the most popular footprint for mid-tier smartphones, and it supports the new standard for Power Class 2 high performance user equipment (HPUE) on band 41.
The QM57508 contains an antenna coupler and 2G PA module that is optimized to overcome the post-PA losses with the most complex handset antenna configurations. It supports three-antenna architectures, has four high-band, five mid-band and seven low-band TRx ports and includes a low-loss, high throw-count switch that supports CA.
The RF Flex family combines performance with design flexibility so phone manufacturers can quickly develop and launch mid-tier smartphones, the largest and fastest-growing segment of the smartphone market. Smartphone manufacturers can customize the RF Flex Gen-5 portfolio by adding Qorvo's premium filters for regional coverage.
RF Fusion design wins in gigabit phone
Four of Qorvo's RF Fusion™ FEMs were designed in a recently launched gigabit phone. Qorvo did not identify the manufacturer, although coincidentally, ZTE announced a gigabit phone at MWC.
Qorvo did identify the FEMs designed in the new phone:
- QM52042 3.5 GHz PA, supporting TD-LTE bands 42 and 43.
- QM7500, which contains multimode, multiband PAs, FDD and TD-LTE T/R switches and filters for bands 38, 40 and 41. The PAs support intra-band uplink and inter-band downlink CA, advanced power tracking and envelope tracking (ET).
- QM78013, which combines multimode, multiband PAs, mode switching, a band 25 duplexer, a multiplexer capable of multi-downlink carrier aggregation for bands 1, 3 and 4, antenna switch and coupler. The PAs support intra-band uplink and inter-band downlink CA, advanced power tracking and ET.
- QM48858 Wi-Fi FEM, integrating a 5 GHz PA, LNA, switch, diplexer, coupler and 2.4 GHz BAW coexistence filter.
Qorvo also announced what they claim as the industry's first 5G RFFE. The QM19000 "delivers high linearity, ultra-low latency and extremely high throughput to meet or exceed the developing requirements of upcoming 5G applications," according to a company release.
Eric Creviston, president of the company's mobile products group, said, "We are proud to introduce the industry's first 5G-capable RF front-end, developed in close collaboration with a leading global chipset provider."
