Direct synthesis of WiMedia UWB signals
Sep 1, 2007
By Iqbal Bawa, K. A. Muralidharan and Joan Mercade Although UWB promises high data rates, creating these signals in the lab and preserving their signal integrity is a highly complex process. One unique method of creating UWB-WiMedia signals uses an arbitrary waveform generator (AWG), yet retains the simplicity of using a dedicated UWB chipset. RF design engineers who use this unique method of AWG-based WiMedia signal generation will have several options, including IQ-baseband, IF and direct-RF-synthesis signal-generation techniques....

Built-in handset antennas enable FM transceivers in mobile phones
Jul 1, 2007
By Peter Lindberg and Andrei Kaikkonen Small form factors and the elimination of wires in favor of cordless peripherals,
such as Bluetooth earpieces, restricts the size and gain of passive antennas that
can be implemented in wireless handsets. However, a unique passive structure
tailored for FM radio and directly interfaced to amplifier circuitry forms an active
antenna module suitable for emerging mobile device applications....
Adopting an RFIC application-programming interface
Jul 1, 2007
By Nick Jungels and Vivek Bhan With increasing integration on RF chips used in cellular handsets, programming
requirements have grown considerably. This increased complexity runs counter
to the ever-tightening life cycle of cellular handsets. One solution is to use a
"hardware" application-programming interface (API). This article will provide
some guidelines for developing an API. Plus, it will focus on pitfalls to avoid, as
well as weigh some of the costs vs. benefits of adopting such an approach....
