Ubidyne will be showcasing its 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. According to Ubidyne, this means the same micro radio technology can be used 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 a fully integrated Doherty MMIC power amplifier with more than 39 dBm peak output power.
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.
