Murata Manufacturing Co., Ltd. has developed and begun mass production on a mobile phone transmission module.
The module is the world's first to integrate the peripheral parts, mainly a SAW filter*1, power amplifier*2 and magnetic stabilizer*3, into one package. It offers a low and compact form as well as extremely high stability under load fluctuation. These characteristics will help to make mobile phone design simpler and less labor intensive, while limiting fluctuation in characteristics when the mobile phone usage environment changes.
The module will be on display at CEATEC JAPAN 2011 at Makuhari Messe in Chiba Prefecture, October 4-8.
Recent years have seen a growing number of frequency bands supporting 3G networks. The more complicated circuit board layouts have made it more difficult to achieve compact design. Murata Manufacturing developed the module putting the SAW filter, power amplifier and magnetic stabilizer in one package to meet the need for compact modules that do not require matching.
|*1 SAW filter:||An element using the characteristics of piezoelectric bodies to get an electrical signal of a certain frequency band|
|*2 Power amplifier:||A semiconductor that amplifies a high-frequency signal in a mobile phone, etc. when that signal is transmitted|
|*3 Magnetic stabilizer:||This load-resistant element is a magnet used in an isolator. It controls fluctuation in characteristics caused by changes in impedance (deviation of antenna characteristics) that occur when the user's hand, metal or other material nears the antenna.|
