  • Calibrated high power radio frequency step attenuator
    Patent number: 6144265
    Abstract: A high power radio frequency(RF) precision step attenuator includes a trim attenuator, a multi-step attenuator and a calibration/control circuit. The control circuit includes a memory for storing attenuator specific calibration data. The calibration data incorporates attenuator characteristics which are used by the control circuit to adjust the attenuator and compensate for manufacturing variances, temperature variations, and the like.
    Type: Grant
    Filed: November 26, 1997
    Date of Patent: November 7, 2000
    Assignee: Honeywell Inc.
