Open-collector Mixer Design for Next Generation RFICs
Nov 1, 2002
By Barry Hunt and Walter Prada Many RF front-end integrated circuit (IC) devices used in today's handsets employ a differential open-collector (OC) output structure for the active mixer stage. This configuration allows the customer flexibility in setting the output impedance, conversion gain, and linearity of the mixer. These front-ends can be used effectively with both differential and single-ended surface acoustic wave (SAW) filter configurations. This article describes techniques for the design of output network circuitry...
Range Estimation for Short-range Event Transmission Systems
Nov 1, 2002
By Alan Bensky Design of short-range wireless event transmission devices, including, for example, security systems, medical emergency buttons and instrument fault detectors as well as remote keyless entry devices, has become relatively easy, thanks to the availability of complete transmit and receive modules and highly integrated chips. However, estimation of system performance, either during the stage of choosing the appropriate module or during actual system design, remains a difficult task....

Comprehending the Technology Behind the UMTS Wideband CDMA Physical Layer
Nov 1, 2002
By Louis Litwin The physical layer of the universal mobile telecommunications system (UMTS) wideband code-division multiple access (WCDMA) standard uses direct sequence spread spectrum (DSSS) modulation with a chip rate of 3.84 Mcps. The channel bandwidth is 5 MHz and this wider bandwidth (compared to 2G systems such as IS-95, which have a bandwidth of 1.25 MHz) has benefits such as higher data rates and improved multipath resolution....

Progress, or Lack of, for That Last Mile
Nov 1, 2002
by Ernest Worthman Technology Editor eworthman@primediabusiness.com In the days before the Internet, xG and GHz computers, the last mile wasn't much of a target of opportunity. Rather it was viewed as simply a communications link that could be filled only by wireless technology. And, in those days, the last mile meant a VHF or UHF (and some 800 MHz) short-haul licensed link that was designed to add telephone-like communications to areas that weren't served by landlines. There was no data, no Internet and no opportunity, perceived or otherwise. Furthermore, in so...
