Komplet front-end IC til kommunikation i 2,4 GHz området

CoreHW og Presto Engineering har samarbejdet om udviklingen af avanceret front-end IC med integreret antenne, der retter sig mod 2,4GHz kommunikation i IoT-enheder (in english).

CoreHW, a leading fabless semiconductor company, and Presto Engineering, a European expert in application specific integrated circuit (ASIC) design, engineering, and production services, have announced their successful collaboration in developing the first enhanced low-power radio frequency (RF) 2.4GHz front-end module in an ultra-small and thin wafer-scale package.

The RF front-end integrated circuit (IC) targets the 2.4 GHz frequency communications band in Bluetooth; Zigbee; Thread; and the industrial, scientific and medical (ISM) internet of things (IoT) devices. It features a high efficiency power amplifier (PA) in the transmit path and a low noise amplifier (LNA) in the receive path.

The circuit is packaged in a very small and thin form factor (2.0 mm x 2.0 mm x 0.5 mm, 16 pin CSP BGA, 0.5 mm ball pitch), with no external matching components needed. It also includes a chip antenna and antenna diversity for enhanced performance. This fully integrated solution is ideal for printed circuit board (PCB) modules used in wireless audio, trackers, smart home devices, access points/gateways, asset management and industrial automation.

Antti Rauhala, CoreHW’s Vice President of Engineering, explains:

- 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 industrialize our IC components for high-volume production.

Cedric Mayor, CEO of Presto Engineering, adds:

- 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. 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.

Presto and CoreHW aims to continue their successful collaboration on future ASIC projects as part of a longer-term engagement program, pushing the boundaries of what is possible in telecommunications technology.
