A power amplifier (PA) is a key part of the RF front-end in transmitters for a local broadband network. Today, commercial PAs are made of III-V HEMT and HBT technology with excellent results. An integrated system-on-chip power amplifier circuit using CMOS technology for cost-effective and spectrum-efficient high-speed wireless communication presents major challenges because power amplifiers hav...

background: in this research, the decomposition of aroclor 1254, including 20 kinds of poly chlorinated biphenyls (pcbs), in real waste transformer oil in the presence of peg1000, naoh, zero valent iron and h2o by microwave (mw) irradiation was studied. methods: central composites design (ccd) method was carried out for experimental design. the effects of microwave power levels (200- 1000 w), r...

Background: Microwave Thermotherapy has been gradually used in radiotherapy and it is reported that microwave radiation increases bone demineralization rate independently of temperature. Furthermore, it becomes more and more widespread that the damage caused by the synergistic effect of microwave radiation and hypergravity. The experiment was designed to investigate the effect of microwa...

Microwaves have typically been used for communications and radar, but nowadays are given much attention to energy transfer applications. This paper describes microwave power transfer from a satellite to Earth that is visualized as a solar power satellite system (SPSS). After the system configuration is explained, unique engineering features are presented. Then, some contributions made by Japane...

This paper represents design methodology of novel phased array antenna and its radiation pattern of 100 elements linear phased array for highly efficient microwave power transmission (MPT) which will be focused on ground based receiving station for microwave power transmission from Space Solar Power Satellite (SSPS) system. Taking different ratio between antenna element spacing, d and wavelengt...

We have performed in situ quasielastic neutron scattering (QENS) measurements on zeolite-guest systems under microwave irradiation, for comparison with corresponding simulations. Both experiment and simulation reveal selective heating of methanol in silicalite, but little to no heating of benzene in silicalite. Effective translational and rotational temperatures extracted from QENS data under m...

Microwave assisted extraction (MAE) tech-nique was employed for the extraction of pectin from black mulberry (Morus nigra) pomace in this research. The effects of process variables namely microwave power (300-900 watt), irradiation time (10-30 min) and liquid to solid ratio (15-30 mL/g) on the yield, degree of esterification (DE) and galacturonic acid content (GalA) of pectin were investigated ...
