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....

Alternative to SMT for microwave and millimeter-wave systems
Jul 1, 2007
By Javed Siddiqui, Dan Sundberg and Dominick Suarez Conventional SMT works well for frequencies up to about 6 GHz. However, at higher frequencies SMT is usually not a viable option because in SMT topology the transmission lines are unshielded, and the components do not have adequate grounding. ...

Direct digital synthesis enables digital PLLs
Jul 1, 2007
By Paul Kern Direct digital synthesis, together with a DAC and a high-performance digital
phase detector, overcome several fundamental drawbacks in analog PLLs, such
as asymmetry in the phase detector or bandwidth limitations and phase noise in
the VCO. Furthermore, because the circuitry is digital, feedback-loop parameters
are adjusted by changing numerical coefficients in device registers rather than
changing electrical parameters in physical components, the latter process being
especially difficult for ASIC designs....

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....
