A 90° power combiner has been used for signal mixing at the intermediate frequency (IF) output port of an image rejection mixer. 1,2 Until now, a passive branch-line coupler was mainly employed for 90° power combining. 1,3 However, the passive branch-line coupler occupies a very large circuit area. For...

Recently, many types of wireless communication systems have rapidly developed and the demand for bandwidth has increased. The spread spectrum communication systems, such as the code division multiple access (CDMA) systems have attracted increasing attention because of their unique features that make it possible to transmit signals through noisy...

In recent years, the 60 GHz band has gained increased interest due to the large amount of license-free and little used frequency spectrum located in the vicinity of 60 GHz. A particular feature of this band is the high attenuation in air, close to 15 dB/km, regardless of weather...
