A Pulsed-measurement Instrument for Device Testing

A recently developed pulsed-measurement instrument that measures the RF large-signal and DC characteristics of discrete GaAs FETs , high electron mobility transistors and integrated devices in GaAs MMICs
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...

A Wideband, Varactor-tuned Microstrip VCO

The design of a varactor-tuned VCO covering an octave frequency range up to 4 GHz and more
A Wideband, Varactor-tuned Microstrip VCO Matjaz Vidmar University of Ljubljana Slovenia When electrical tuning of an oscillator is required over a wide microwave frequency range, yttrium iron garnet (YIG)-tuned oscillators usually provide the widest frequency coverage as well as relatively low phase noise. While YIG-tuned oscillators generally provide a...
