Relec Electronics has helped develop an emergency back-up power system for a new range of LED surgical lighting products. The team supplied a DRU30-24 DIN Rail Mount UPS Controller, that interfaces between the power supply, back up battery and load to maintain the battery in prime charged condition and ensure a seamless transition to battery power in the event of mains failure. Linear Technology has announced the LTC5549, a double-balanced mixer that can operate either as an upconverter or downconverter, with a very wide RF frequency range from 2GHz to 14GHz. The mixer's performance is said to enhance a range of microwave applications, including microwave backhaul, high unlicensed band LTE-Advanced base stations, satellite broadband radios, radar systems, X-band and Ku band transceivers, test equipment and satellite modems.
