Ubidyne, a developer of wireless dynamic digital active antenna technology, will be showing off its chip-based power amplifier solution for active antenna design at the LTE Summit later this month in Barcelona.

The company says its P-Chip powers its latest micro-radio transceiver and delivers scalable output power solutions for both small-cell and macro-cell active antennas. “This means that radio equipment vendors and mobile network operators can benefit from economies of scale by using the same micro radio technology for any size of mobile operator cell array and network standard,” company literature says.

The tech talk: Based on the Doherty amplifier design, a single transceiver provides output power between 0.8 watts and 6.4 watts by parallel use of P-Chips. For example, an array with 16 micro radios can easily exceed the output power of 2×40 watts of today’s available remote radio heads.

“The P-Chip is the only fully integrated Doherty MMIC (monolithic microwave integrated circuit) power amplifier with more than 39 dBm peak output power,” Ubidyne adds. “With high levels of integration and few external components, Ubidyne’s P-Chip provides low-cost transceiver solutions for the telecom equipment market across a wide range of mobile operator requirements.” ?
