Accurately measuring the power in wideband signals used in 3G and pulsed systems requires a power meter with a high bandwidth. To address this market condition, the ML2487A (single-channel) and ML2488A (dual-channel) high speed peak power meters have been developed that feature 20 MHz channel bandwidth, which is a...

Splitting an RF input signal within a VCR or television was never much of a design challenge for manufacturers when the signal was analog. That changed dramatically, however, when CATV systems made the transition from analog to digital to provide addressability, video on demand, Internet access and other services....

Philadelphia was a good and gracious host for Microwave Week as weather-weary visitors enjoyed somewhat milder spring-like weather for the 2003 IEEE MTT-S International Microwave Symposium held June 8 to 13. The overall turnout was good with over 10,000 delegates, visitors and exhibitors attending the annual event. The city...

The rising demand for low cost, low power personal communication systems operating up to 6 GHz makes the integration of radio frequency subsystems on monolithic silicon substrates an attractive challenge. Deep sub-micron technology allows silicon CMOS or silicon-germanium (SiGe) integrated circuits (IC) to operate at frequencies well within the...

Semiconductor varactor diodes are commonly used throughout RF, microwave and millimeter-wave spectrums for a variety of applications, 1,2 including the tuning of critical circuits such as voltage-controlled oscillators (VCO), filters, matching networks and phase-shifters in RFIC and MMIC circuits. However, semiconductor varactor diodes are limited in their applications by...
