Webnormally used in AlGaAs/InGaAs pHEMTs, which will provide a higher off state breakdown and benefit the high voltage operation. The quality of ohmic contact directly impact the RF swing and efficiency of the power amplifier. In the current CS1 AlGaAs/InGaAs pHEMT2 flow, hypoeutectic AuGe/Ni ohmic contact process is utilized [1]. For WebFully oxidized pHEMTs and unoxidized control sample were fabricated at the same time. Low subthreshold leakage current, sharp transconductance turn on near pinch-off and high output impedance were observed for fully oxidized GOI pHEMTs due to the introduction of the insulating oxide buffer.

Abstract: This paper reviews current understanding of reliability of InP HEMTs and GaAs PHEMTs. … WebGaN PHEMTs switches are used to design this attenuator. The simulated results show the total attenuation range from 0.5dB to 31.5dB. Worst case insertion loss of ~ 3 dB is achieved for all the six bits of the attenuator over entire operating frequency band. All practical aspects of the design are incorporated while doing simulations.
WebThe degradation of GaAs MESFETs and PHEMTs in hydrogen atmospheres has commanded significant attention over the past several years [4]. The effect was first reported in MESFETs by Camp et al [5] in 1989, and has been observed more recently by others in MESFETs [6,7,8], PHEMTs [2,3,9], and InP HEMTs [10]. pHEMTs are extensively used in monolithic microwave-integrated circuits.
