Comprehending the Technology Behind the UMTS Wideband CDMA Physical Layer
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....

Open-collector Mixer Design for Next Generation RFICs
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...
