Freescale Semiconductor’s two new LDMOS RF power transistors allow wireless base station amplifiers to cover all channels in an entire allocated frequency band. The transistors are internally matched with low capacitance to simplify circuit design and have integrated electrostatic discharge protection. Their broad gate-source voltage range of -6 to +10V increases their … [Read more...]
'Magic Skin' Could Make Aircraft EMI- and Lightning-Proof
NASA has awarded Cessna Aircraft Co. a $1.9 million development contract for its self-healing “magic skin” for future aircraft. The idea is to pad the entire airliner with energy-absorbing foam, then slide the skin along the plane’s body. Once on, the snug-fit casing would protect the vehicle from impact damage, lightning strikes, electromagnetic interference and temperature … [Read more...]
