Murata today announced the HFQPRAPCA series of RF wireless modules designed specifically for mobile phone applications and comprising a SAW filter, power amplifier and magnetic stabilizer. Believed to be the world’s first module to combine the three components as a single package, it measures just 6.6 x 3.8 x 1.0 mm and aids cellular phone engineers achieve a more integrated and compact design.

The magnetic stabilizer, that provides the same function as an isolator, aids the modules ability to be very stable under fluctuating load conditions. 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.

With the growing numbers of frequency bands supporting 3G networks, mobile phone manufacturers have found it increasingly difficult to achieve a compact design. Murata Manufacturing designed the single package module to meet the designer’s need for a compact integrated module that does not need matching.

The HFQPRAPCA series is available to support the following bands; Band 5 (BC0), Band 1 (BC6), Band 25 (BC14) and Band 13. Further frequency bands will be supported in the future.
