CoreHW, a fabless semiconductor company, has successfully collaborated with Presto Engineering, a European specialist in application-specific integrated circuit (ASIC) design, engineering, and production services, to develop the first advanced low-power radio frequency (RF) 2.4GHz front-end module within an ultra-compact wafer-scale package.
This RF front-end integrated circuit (IC) is designed for use in the 2.4 GHz frequency band, targeting Bluetooth, Zigbee, Thread, and the industrial, scientific, and medical (ISM) IoT devices. The circuit boasts a highly efficient power amplifier (PA) in the transmit path and a low noise amplifier (LNA) in the receive path. It is housed in an exceptionally small and thin package (2.0 mm x 2.0 mm x 0.5 mm, 16-pin CSP BGA, 0.5 mm ball pitch) that requires no external matching components.
Additionally, it incorporates a chip antenna and antenna diversity, ensuring superior performance. This fully integrated solution is ideally suited for printed circuit board (PCB) modules utilised in wireless audio, trackers, smart home devices, access points/gateways, asset management, and industrial automation.
“Efficient collaboration with Presto Engineering has led to the successful volume production of our first RF switch component (CHW1010). Now, the next-generation RF front-end module (FEM) components are targeted for full qualification in Q4 2024. The collaboration has been seamless, and Presto’s technical team has once again demonstrated their capability to industrialise our IC components for high-volume production,” said Antti Rauhala, Vice President of Engineering at CoreHW.
“The CHW3021 marks our second collaboration with CoreHW, underlying the importance of establishing long-term partnerships to efficiently harness each other’s strengths in ASIC development,” added Cedric Mayor, CEO of Presto Engineering. “Drawing from our extensive experience in industrializing and producing high-volume RF chipsets, we are well-equipped to bring industry best practices to CoreHW. This collaboration ensures a seamless product release to the market.”
Both CoreHW and Presto Engineering are enthusiastic about continuing their successful partnership on future ASIC projects as part of a long-term engagement programme, driving innovation in telecommunications technology.
