Skyworks offers a high-efficiency RF front-end power management IC designed for the SkyBlue™ System, and for APT RF power amplifier (PA) applications in portable battery powered devices such as smartphones, tablets, and eBook readers. The SKY87020-12 provides a 4.5 V bias supply for RF PA operation with load up to 3 mA, and is available whenever the device is enabled. The VIN supply is bypassed to the 4V5 output when the device is disabled.
Skyworks offers a large variety of RF and microwave semiconductor products for use in medical devices. Common applications include glucose monitoring, defibrillators, hearing aids, pacemakers, MRI scanners, and others.
Skyworks’ recently unveiled the industry’s first stand-alone, high dynamic range power detector for use in data cards and smart phones in conjunction with Skyworks’ power amplifiers in 3G and LTE applications. The detector offers state-of-the-art reliability, temperature stability, and ruggedness due to it being manufactured with Skyworks’ gallium arsenide heterojunction bipolar transistor process. The detector circuit technology is optimally aligned for transceivers that require external detection for power control. Exceptional temperature and voltage compensation maintains accuracy over extreme operating conditions. The detector presents high off-state impedance to the transceiver to minimize loading other detectors connected to the input line. The SKY77002 is packaged in the quad flat no-lead package and is fully compliant with current restriction of hazardous substances requirements.
