Designed specifically for mobile phones, the HFQPRAPCA RF wireless modules by Murata comprise a SAW filter, power amplifier and magnetic stabiliser. Believed to be the world's first module to combine the three components as a single package, it measures just 6.6x3.8x1mm. The magnetic stabiliser provides the same function as an isolator, and aids the modules ability to be very stable under fluctuating load conditions, says the company. Its load-resistant element is a magnet used as an isolator. It controls the characteristics of load fluctuation caused by changes in impedance that can occur when the user's hand, metal object or other materials come close to the antenna. The modules are available to support: Band 5 (BC0), Band 1 (BC6), Band 25 (BC14) and Band 13.
