US Patent:
59907525, Nov 23, 1999
Filed:
May 14, 1998
Appl. No.:
9/079085
Inventors:
Harold Papazian - Northbrook IL
Glen O. Reeser - Palatine IL
Lunal Khuon - Bolingbrook IL
Edward Bruzgo - Mundelein IL
Sang Kim - Cicero IL
Assignee:
CTS Corporation - Elkhart IN
International Classification:

H01P 708
US Classification:
331 96
Abstract:
A method (100) for mechanically tuning a VCO that has a resonant stripline having vias in predetermined locations connected through a circuit board to ground. This includes a step (104) of measuring the operating frequency of the VCO. A following step (106) includes calculating an amount of frequency shift needed to achieve a desired frequency. A following step (108) matches the amount of frequency shift needed to values in a look-up table of frequency shifts versus via locations to determine which vias locations will provide the proper amount of frequency shift. A last step (110) includes mechanically disconnecting from ground the via locations indicated in the third step such that the desired frequency is achieved. This method (100) of tuning allows VCO frequency adjustment after final assembly avoiding problems of frequency shifts that can occur due to the placement of a metal lid on the circuit board after assembly.
