Skyworks Solutions Inc. expanded its product portfolio by adding high dynamic range power detectors for smart phones and datacards. Skyworks’ RF detectors are an industry first and address the market’s need for small, stand-alone solutions that are compatible with various baseband architectures and accommodate multiple 3G and LTE band combinations. In addition, these innovative devices have been designed to work with the SKY7770X and SKY7772X series of 3G and 4G power amplifiers to expand the compatibility of the integrated daisy chain coupler for the majority of basebands and transceivers.

The detectors’ small size (1.2 x 1.5 mm) minimizes board space requirements, while their higher dynamic range increases power control and improves total radiated power performance. Their low current consumption enables both longer standby and talk times, and their high off-state impedance level is particularly beneficial for today’s demanding, high-end 3G smart phones.

“We are delighted to once again be at the forefront of technology innovation,” said Gregory L. Waters, Executive Vice President and General Manager of Front-end Solutions at Skyworks. “Skyworks’ new power detectors are highly compatible with other solutions from our portfolio and allow us to offer our customers a full end-to-end solution for smart phones and data cards.”

The SKY77002 is a stand-alone, high dynamic range power detector designed for use in smart phones and data cards in conjunction with Skyworks’ power amplifiers in 3G and LTE applications. The detector is manufactured with Skyworks’ gallium arsenide heterojunction bipolar transistor process offering state-of-the-art reliability, temperature stability and ruggedness. The SKY77002 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.
