Press Release Summary:

May 25, 2012 - Intended for small-cell and macro-cell active antennas, Micro Radio Transceiver provides output power from 0.8-6.4 W by parallel use of P-Chips. Each P-Chip Doherty MMIC power amplifier delivers more than 39 dBm peak output power. Based on micro radio, uB700 Active Antenna System supports 4G in 700 MHz digital dividend band for broadband mobile networks, while uB900 supports GSM, UMTS, and LTE in 900 MHz band. Each micro radio can be controlled digitally and independently by central hub.

Ubidyne's New Micro Radio Delivers Scalable Output Power Performance for Small and Macro Cell Active Antennas

Press release date: May 15, 2012

Ubidyne launches its latest active antenna system release 3.5 at LTE Summit

Ubidyne, a leading developer of dynamic digital active antenna technology for wireless communications, is showcasing its unique chip-based power amplifier solution for active antenna design at the LTE Summit later this month in Barcelona. Ubidyne's new P-Chip is at the heart of 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.

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. 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.

Release 3.5 of Ubidyne's Active Antenna System solution featuring the new P-Chip micro radio is being launched at the LTE Summit next week. 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 .

"The P-Chip sets a new standard for micro radio design, delivering un-matched performance, flexibility and economies of scale for use in both macro and small cell active antenna solutions," said Michael Fränkle, CEO of Ubidyne. "We are now able to offer radio equipment vendors a powerful, cost-effective solution that can be configured precisely to meet the needs of mobile operators for all standards and cell sizes."
