Characterization of a Double-doped Power HJFET for W-CDMA Cellular Handset Application Demands on next-generation wideband CDMA (W-CDMA) handset transmitters (and thus power devices) include high linearity and high power-added efficiency (PAE) under low voltage supply. A power heterojunction FET (HJFET) has been developed for such applications, achieving a high...

Planar Integrated Antenna Technology Over the last several decades, the development of planar antenna technology has fundamentally changed the microwave and millimeter-wave communication fields. Planar antennas can be printed on dielectric substrates with minimal cost and processing. In many applications, these compact and low profile antennas offer an inexpensive...

Correlation between Ungated Recess Width and Linearity of GaAs MESFETs Intermodulation distortion and adjacent-channel power ratio (ACPR1) performance of GaAs MESFET discrete and MMIC power amplifier (PA) devices has been found to be dependent on the width of the ungated recess. Devices with wide ungated recess exhibit soft gain...
