Fraunhofer IIS has proposed and demonstrated "Full-HD Voice", an implementation of the AAC-ELD (Advanced Audio Coding – Enhanced Low Delay) codec for LTE handsets.  Where previous cell phone voice codecs only supported frequencies up to kHz and upcoming wideband audio services branded as HD Voice up to 7 kHz, Full-HD Voice supports the entire bandwidth range from 20 Hz to 20 kHz. For end-to-end Full-HD Voice calls to succeed however, both the caller and recipient's handsets as well as networks have to support the feature. 
From the relatively low power MMIC (typically less than 2 watts output power), to the medium power RF stage (either a connectorized hybrid design or a thermally-enhanced surface mount integrated circuit package), to the highest power pallets, enclosed modules and rack-mount units, Richardson RFPD offers a full range of RF & MW Power Amplifiers. Our main suppliers include ANADIGICS , NXP Semiconductors , M/A-COM Technology Solutions , Microsemi , and United Monolithic Semiconductors . Please note that we also supply the accompanying Thermal Management Systems designed to help cool RF & MW power amplifiers.
