Concealing narrow-bandwidth antennas inside a mobile device gets tricky when they need to be tuned for different services—from cell phone to Bluetooth to WiFi to mobile TV. Peregrine Semiconductor Corp. (San Diego, Calif.) claims to be unveiling the first single-chip solution at Electronica 2008 (Munich, November 11-14, 2008). Peregrine's digitally tunable capacitor chip aims to adjust a mobile antenna's radio-frequency (RF) response to all the different bands mobile media devices receive today. Potentially, it can also dynamically tune even for environmental changes—countering effects like touching your finger to the antenna.
