2.3 V operation GaAs power MESFET with 68% power-added efficiency

Proceedings of 1994 IEEE GaAs IC Symposium, 2005
A state-of-the-art GaAs power MESFET operating at a drain bias of 2.3 V has been developed using the low-high doped channel structure. The device has 0.8-/spl mu/m gate length and 21-mm gate width. The power performance tested at a 2.3 V drain bias under 900 MHz operation frequency was output power of 31.3-dBm with 11.3-dB gain and 69-percent power ...

Class-B power MMIC amplifiers with 70 percent power-added efficiency

IEEE Transactions on Microwave Theory and Techniques, 1989
C-band monolithic amplifiers using high-efficiency, refractory metal, multifunction-self-aligned-gate (MSAG) processing have been designed, fabricated, and tested. The class-B single-ended amplifier design uses reactive termination for higher order harmonics and achieves a power-added efficiency (PAE) of 70% with associated gain of 8 dB and output ...

Efficient coloring of Wireless Ad Hoc Networks with diminished transmitter power

Proceedings of the International Multiconference on Computer Science and Information Technology, 2010
In our work we present a new approach to the problem of channel assignment in Wireless Ad Hoc Network. We introduce a new algorithm which works in distributed model of computations on Unit Disc Graphs modeling theWireless Ad Hoc Network. The algorithm first modifies the transmitting power of the devices constituting the network (radii of the vertices ...

Distributed power control for power-aware energy-efficient routing in ad hoc networks

2002
A BSTRACT In this paper, a distributed power control mecha- nism for ad hoc networks is proposed and investigated. This mechanism, acting at different layers, reduces the power consumption maintaining similar behavior, in terms of delay and throughput, as classic schemes. In the proposed strategy, the generic sender uses an appro- priate power level to
