Design Benefits of Silicon MMICs Philips Semiconductors Eindhoven, The Netherlands Monolithic microwave integrated circuits (MMICs) were developed originally to deliver cost-effective, low voltage and high performance RF solutions to the mobile communications market. Until recently, common belief held that MMICs needed to be manufactured from GaAs. However, as a...

A Pulsed-measurement Instrument for Device Testing GaAs Code Ltd. Linton, Cambridge, UK For many discrete GaAs FETs, high electron mobility transistors (HEMT) and integrated devices in GaAs MMICs, the large-signal IV characteristics of the device at RF, microwave or mm-wave frequencies are very different from the DC characteristics. This...

New Microwave Signal Generators that Adapt to Wide-ranging Tasks Tektronix Inc. Beaverton, OR Flourishing digital wireless technologies, in addition to bread-and-butter RF applications such as radar design and electromagnetic susceptibility testing, have created a need for simpler, more cost-effective RF signal sources. As a result, new solutions have emerged...
