PLL/Synthesizer Includes VCO

Crystek Corporation’s (Fort Myers, FL) CPLL66 family is the company’s first foray into the PLL/Synthesizer market. Designed for digital radio equipment, fixed wireless access, satellite communications systems, base stations, personal communications systems, portable radios, and test instruments, the CPLL66 is a complete PLL/ Synthesizer that only needs an external frequency reference and supply voltages to operate the internal PLL (phase lock loop) and VCO (voltage controlled oscillator).

A Software Development Process for Small-Scale Embedded Systems

Developing software for small-scale embedded applications is different from developing large-scale software applications. Large-scale applications use commercially available ‘one fits all’ software development solutions that are difficult to scale downward and usually miss the desired process goals. In many cases, developing a small-scale software application development process within an existing corporate environment is quicker, less expensive, and results in superior developer productivity and product quality.

Choosing Among ZigBee RF Power Options for Your Wireless Application

While often associated with home automation, the new ZigBee wireless data standard is making fast inroads into industrial, military, and aerospace applications. By supplying highly reliable, wireless mesh networking at very low cost, ZigBee enables improvements to traditional sensing and monitoring applications, and enables new applications that would otherwise be impractical.

F-35 Antenna Measurement Program

Engineers are conducting sophisticated performance testing of F-35 Joint Strike Fighter (JSF) antennas at the AFRL Newport Research Facility, New York. Through an agreement with the F-35 Joint Program Office, engineers from Lockheed Martin and AFRL's Rome Research Site are collaborating on the test effort. Because antenna testing is occurring early in the aircraft development cycle, the team is using a model—a full-scale F-35 replica—to measure the installed performance of the aircraft's communications, navigation, identification, and electronic warfare antennas. The goal of this testing program is to optimize antenna performance and identify and correct antenna problems before the aircraft design is finalized and antenna system changes consequently become more difficult and expensive to incorporate.
