Cooperation on Wireless Charging Solutions: ROHM Group Company LAPIS Technology and Global Antenna Manufacturer Shanghai Amphenol Airwave Join Forces

ROHM Group Company LAPIS Technology and Global Antenna Manufacturer Shanghai Amphenol Airwave Join Forces

Providing one-stop support for implementing wireless charging functions for hearable and wearable devices

ROHM Group company LAPIS Technology Co., Ltd., and global antenna manufacturer Shanghai Amphenol Airwave Communication Electronics Co., Ltd. (a subsidiary of Amphenol Corporation), today announced they have established a cooperative framework to provide wireless charging solutions for hearable and wearable devices that are trending towards greater compactness and sophistication.

Advanced antenna customization technology allows Shanghai Amphenol Airwave to provide compact antennas that meet the needs for smaller, thinner housings in the hearable and wearable device markets. At the same time, LAPIS Technology provides compact, high-performance, wireless power supply ICs that leverage wireless digital and analog circuit technologies cultivated over many years through LSI development.

With technical support provided by LAPIS Technology, Shanghai Amphenol Airwave will provide a wireless charging solution that solves design constraints regarding housing, along with issues such as an increased development workforce. The reference design matches power transmission and reception centered on the antenna and wireless charger IC. This contributes to rapid device development by providing one-stop support to global customers for achieving wireless charging functionality.

Sally Yin, General Manager, Shanghai Amphenol Airwave Communication Electronics Co., Ltd “Partnering with LAPIS Technology allows Shanghai Amphenol Airwave to provide value-added wireless charging solutions. This will enable customers to further reduce size, along with development lead times. Shortening development lead time in particular is one of the major advantages for new product development. We are extremely pleased to be able to improve customer satisfaction even more through these benefits.”

Sumihiro Takashima, President, LAPIS Technology Co., Ltd. “We are honored to work with Shanghai Amphenol Airwave, a leader in the antenna industry, to provide novel solutions to our customers. By combining with our products, we are confident that we can provide the most efficient solutions to meet the challenges facing the market.”

Overview of Each Company’s Technologies

1. Shanghai Amphenol Airwave’s Antenna Technology

Shanghai Amphenol Airwave’s thin, compact antenna design is made possible through experience and expertise cultivated over many years. One key strength is the ability to propose antennas suitable for 3D enclosures, centered on LDS and FPC types. This makes it possible to place the antenna along the housing, which is difficult to achieve with PCB antennas. The result is not only improved design quality, but greater space savings that contributes to set miniaturization.

2. Wireless Charging Technology from LAPIS

LAPIS Technology’s wireless charging chipsets incorporate the control circuitry necessary for transmitting and receiving power, leading to smaller system size and shorter lead times by eliminating the need to develop MCU programs. In addition, using the 13.56MHz frequency band (same as NFC) for power transmission and reception supports even smaller antennas.

Terminology

Matching

Involves adjusting the transmission and receiving antennas to reduce energy loss. This requires technological expertise in antenna design and board layout.

Near Field Communication (NFC)

A short-range wireless communication technology that uses the 13.56MHz frequency band.

Laser Direct Structuring (LDS)

A process technology that allows antennas to be manufactured on 3D plastic. This eliminates the need for antenna components, making it ideal for smaller sets.

Antennas

PFC types are thinner, lighter, and more flexible than PCB antennas. PCB antennas are mounted directly on the printed circuit board (PCB). They can be integrated with electronic circuits to reduce manufacturing lead time.
