Abstract

Claims (25)

1 . A connection device comprising:

a first interface including a signal connector configured for connection with a signal source;

a second interface including an antenna to transmit and receive a wireless radio frequency signal;

a first switch between the first interface and the second interface;

a second switch between the first switch and the second interface, the second switch having a calibration mode and having an operation mode; and

wherein in the calibration mode, the second switch is configured to direct a signal from the signal source to an equivalent antenna and, in the operation mode, the second switch directs the signal from the signal source to the antenna.

2 . The device of claim 1 wherein the calibration mode is selected when the antenna is activated.

3 . The device of claim 1 further including a controller coupled to a gain selector with a selectable gain factor, the gain selector coupled to the second interface through the first switch, wherein the controller provides a controller output corresponding to the selected gain factor.

4 . The device of claim 3 wherein the controller output is based on a comparison of a reference signal strength and a signal strength sensed at the second interface.

5 . The device of claim 3 wherein the controller is coupled to the second interface by a power detector.

6 . The device of claim 3 further including a temperature sensor coupled to the controller and wherein the controller output is based on a temperature.

7 . The device of claim 3 further including a supply voltage sensor coupled to the controller and wherein the controller output is based on a supply voltage.

8 . The device of claim 3 further including a signal detector coupled to the first interface and coupled to the controller, the signal detector configured to provide a detected level corresponding to the signal at the first interface and wherein the controller output is based on the detected level.

9 . The device of claim 8 wherein the signal detector includes a comparator.

10 . A method comprising:

providing a first interface for coupling to a signal source;

providing a second interface including an antenna for transmitting and receiving a wireless radio frequency signal;

providing a first switch and a gain selector coupling the first interface and the second interface; and

providing a second switch between the first switch and the second interface, the second switch having a calibration mode and an operation mode,

wherein in the calibration mode, the second switch is configured to direct a signal from the signal source to an equivalent antenna and, in the operation mode, the second switch is configured to direct the signal from the signal source to the antenna.

11 . The method of claim 10 further including configuring the second switch to enter the calibration mode upon activating the antenna.

12 . The method of claim 11 further including configuring the second switch to enter the operation mode after the calibration mode.

13 . The method of claim 10 wherein configuring the second switch for the calibration mode includes providing a controller configured to provide the gain factor signal.

14 . The method of claim 13 further including configuring the controller to detect a signal strength at the second interface, detect a signal level at the first interface, receive a temperature signal, receive a supply voltage signal, and/or calculate a difference.

15 . The method of claim 14 further including configuring the controller to compare the signal strength and a reference signal strength.
