This work presents two different approaches for the implementation of pseudomorphic high electron mobility transistors (pHEMTs) and planar Gunn diodes on the same gallium arsenide substrate. In the first approach, a combined wafer is used where a buffer layer separates the active layers of the two devices. A second approach was also examined using a single wafer where the AlGaAs/InGaAs/GaAs het...
Modern medical microwave diagnostic equipment requires the use of solutions related to compactness developed devices and high performance. It is possible achieve set conditions with a modern semiconductor component base based on A3B5 compounds. The paper presents designs main control elements signal as part radiothermometer monolithic Al-GaN/GaN/SiC HEMT SPDT transistor switch MIC LNA basis pHE...
In order to meet the demand for mass production of 77GHz automotive radar systems, a low cost and high performance 38/77GHz AlGaAs/InGaAs PHEMT MMIC transmit amplifier with a multiplier has been realized. The chip is packaged in an inexpensive conventional non-hermetic package. Excellent power performance is demonstrated with a 15 dBm output power and 7 dB maximum conversion gain from 38 to 76....
