We see from your search that you're looking for information on the term "Personal digital assistants",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Battery contacts ensure reliable retention from
Components Corporation, which we summarised at the time by saying "Battery contacts are ideally suited for employment in space-constrained wireless communications, mobile computing, consumer and industrial applications in which weight and size are
factors".
A few weeks before,
we featured the news release Transceivers integrate full WiMAX feature set from
Analog Devices: "The power and space savings of the AD9354 and AD9355 enable manufacturers to incorporate WIMAX functionality into handsets, thumb drives or PCMCIA cards".
In August 2007, we covered the news from Rogers Corp
concerning its R/flex Jade A
- take a look at Laminate system cleans up flex circuit designs
which says: "Halogen-free transparent epoxy polyimide laminate system is safe for the environment and delivers superior performance in an all-inclusive package for flexible circuit designs".
Take a look also at the news release from STMicroelectronics, Alliance targets Digital Radio Mondiale expansion,
as well as Logic devices ease MCU I/O expansion from STMicroelectronics,
and Emergency services use wireless broadband from Qualcomm.
