Filed:

Feb 25, 2003

Appl. No.:

10/373353

Inventors:

John Gibbs - Lynnwood WA, US

Assignee:

ICOM America, Incorporated - Bellevue WA

International Classification:

H04B 1/06

US Classification:

455260, 455 76, 455112, 455216, 375375, 375373

Abstract:

Frequency synthesizer utilizing fractional-N synthesis includes a phase detector having an input receivable of a reference frequency, a loop filter arranged to receive the signal from the phase detector, a tunable oscillator arranged to receive a tuning signal generated by the loop filter and provide an output frequency and an integer divider arranged to receive the output frequency of the oscillator, divide it by a division control number (N+F) and provide the divided output frequency to the phase detector. The division control number is made up of an integer (N) and a fraction portion (F) separated into at least two different fractions. The fraction portion is generated by at least two sigma-delta converters, each processing a respective fraction with the sigma-delta converter processing a smaller fraction being driven at a lower clock rate than a sigma-delta converter processing the largest fraction. By driving the sigma-delta converter which processes a smaller fraction at a reduced clock rate, the sigma-delta converter can consume less power and be manufactured at reduced cost.

Abstract:

An on-board measurement system includes a plurality of measurement modules each provided with internal or external transducers and a control module for conducting desired testing procedures. The modular logging apparatus is removably secured to a product undergoing a manufacturing process or the like whereby numerous or substantially continuous measurements can be made of environmental factors affecting a product. The control module also receives and stores measured data for later retrieval.
