Mitsubishi develops 220W GaN-HEMT for 4G
Mobile Communication Base Transceiver Stations For BTS small size and low power consumption by high performance
Mitsubishi Electric has developed a 220W-output power GaN HEMT, which it claims offers world-leading efficiency for 2.6GHz-band Base Transceiver Stations (BTS) of 4G mobile communication systems.
Samples will be released starting November 1.
High-speed 4G mobile communication systems including Long Term Evolution (LTE) and LTE-Advanced incorporate are being equipped with progressively smaller BTS for macro-cells to increase data capacity and to reduce power consumption.
Mitsubishi Electric's new GaN-HEMT is expected to help realise even smaller and lower-power BTS.
Product features include a drain efficiency of 74 percent, which results in simpler cooling system, which reduces BTS size and power consumption. It also comes in a flangeless ceramic package to reduce size.
Going forward, the lineup will be further with products for different outputs and frequencies, as well as adapted for mobile communication systems beyond 4G.
