A design method of microwave circuits eased on software defined radio concept

The Software Defined Radio (SDR) which is a recently proposed technology concept and has attracted the attention of many communication engineering researchers, will be one of the most important technologies in advanced communication and broadcasting systems on 21st century. This is mainly due to a great advancement in digital and programmable devices and circuits. Although SDR has several attractive features, there are also a lot of design issues even in microwave circuits, which are basically analog and non-reconfigurable. On 21st century RF transceivers should be designed from a system level viewpoint, e.g. system gain and optimum system power consumption design
