Micro radio delivers scalable output power performance for small and macro cell active antennas

May 16, 2012 // By Julien Happich
Ubidyne has launched a unique chip-based power amplifier solution for active antenna design.

P-Chip is at the heart of the company's 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. Based on the Doherty amplifier design, a single transceiver provides output power between 0.8W and 6.4W by parallel use of P-Chips. For example, an array with 16 micro radios can easily exceed the output power of 2x40W 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, claims the manufacturer. 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.

All Ubidyne active antenna solutions feature one transceiver or micro radio per antenna radiator to deliver significant performance benefits. The uB700 supports 4G (LTE) in the 700MHz digital dividend band for broadband mobile networks, while the uB900 supports GSM, UMTS and LTE in the 900MHz frequency band to address mobile networks in Europe, Africa, Oceania, Asia and the Middle East. Ubidyne is also developing an 800MHz solution and in the near future will support high-band up to 2.6GHz as well as multi-band requirements.
Ubidyne's micro radio is the main building block of its active antenna architecture, comprising a complete transceiver that can be used multiple times in a macro antenna array. Each micro radio can be controlled completely digitally and independently by a central hub which enables advanced features like beamforming and electronic tilting as well as a self-healing capability that significantly reduces OPEX for mobile network operators .
