The article features several products for technology designers. Designed to support 54'Mbit/sec applications, SiGe Semiconductor's RangeCharger SE2521A40 RF front-end module enables efficiency and low power consumption for embedded WLAN, including WiFi VoIP phones. National Semiconductor's LP3947 USB/AC charge management system and LM3655 battery protection IC for embedded Lilon and LiPoly batteries are suitable for use in cell phones, digital still cameras, MP3 players, PDAs, and handheld instrumentation. Cypress Semiconductor's CYIWOSC3000A camera-phone imager is a 1/3-inch optical format sensor with an active pixel array format of 2,048x1,536 pixels. Meanwhile, Telchemy's VQmon 2.2 VoIP performance management technology supports the measurement of key performance parameters for push-to-talk and other near-real time applications.
