The fabrication and performance of 160-nm gate-length metamorphic AlInAs/GaInAs high electron mobility transistors （mHEMTs） grown on GaAs substrate by metal organic chemical vapour deposition （MOCVD） are reported. By using a novel combined optical and e-beam photolithography technology, submicron mHEMTs devices have been achieved. The devices exhibit good DC and RF performance. The maximum current density was 817 mA/mm and the maximum transconductance was 828 mS/mm. The non-alloyed Ohmic contact resistance Rc was as low as 0.02 Ω- ram. The unity current gain cut-off frequency （fT） and the maximum oscillation frequency （fmax） were 146 GHz and 189 GHz, respectively. This device has the highest fT yet reported for a 160-nm gate-length HEMTs grown by MOCVD. The output conductance is 28.9 mS/mm, which results in a large voltage gain of 28.6, Also, an input capacitance to gate-drain feedback capacitance ratio, Cgs/Cgd, of 4.3 is obtained in the device.

As the demand for broadband multimedia wireless is increasing, there is a great need for quality of service (QoS). The IEEE 802.11e workgroup proposes the hybrid coordination function (HCF) channel access mechanisms, which includes two mechanisms: enhanced distributed channel access (EDCA) and HCF control channel access (HCCA). The EDCA is a contention-based scheme and supports service differentiation through prioritiesed access to the wireless medium. The HCCA works under the control of a hvbrid coordinator (HC) and provides a centralised polling scheme. In this paper, we evaluate and compare the performance of HCCA and EDCA for constant bit rate (CBR) traffic transmission. The results show that both access methods are able to carry the prioritized traffic.
