The Monopoly of Quartz

by Ramon M. Cerda, VP of Engineering Crystek Corporation Quartz-based oscillators (crystal oscillators) have a virtual monopoly in the electronic industry as the premier frequency-control source of choice. This monopoly goes back nearly 100 years. Today, there is still no other frequency-control technology that comes close in terms of volumes produced each year. The quartz crystal oscillator […]

LDMOS Stakes Its Ground in L-band Radar Upgrades

by David Lewicki, Military Products Manager, RF Power NXP Semiconductors News stories about military radar systems today focus on their use of gallium nitride (GaN) as their source of RF power, which isn’t surprising as virtually all next-generation military radars operating at S- and X-bands will be based on the Active Electronically-Steered Array (AESA) architecture, for which […]

The Opportunities and Challenges of LTE Unlicensed in 5 GHz

by David Witkowski, Executive Director Wireless Communications Initiative n 1998, the Federal Communications Commission established the Unlicensed National Information Infrastructure or U-NII 5 GHz bands.
