Abstract

An EHF communication system including an EHF communication chip. The EHF communication chip may include an EHF communication circuit having at least one controllable parameter-based module having a testable and controllable operating parameter The EHF communication chip may further include a test and trim circuit coupled to the EHF communication circuit, where the test and trim circuit includes a logic circuit having one or more memory elements, where the logic circuit is coupled to the controllable parameter-based module.

Claims

1. A system comprising:

a control circuit coupled to an extremely high frequency (EHF) communication circuit via a control interface, the control circuit configured to;

determine a reference value of a target parameter of the EHF communication circuit;

receive information describing an actual value of the target parameter of the EHF communication circuit via the control interface;

receive comparison information describing a comparison of the determined reference value and the information describing the actual value of the target parameter; and

receive, via the control interface, information indicating a determination of whether to modify a temporary control setting associated with the target parameter.

2. The system of claim 1, wherein the control circuit is further configured to modify the temporary control setting by a specified adjustment value when the comparison information indicates that the actual value of the target parameter exceeds the target parameter tolerance level.

3. The system of claim 2, wherein the control circuit is further configured to:

compare the specified adjustment value to an adjustment threshold;

receive an adjusted actual value of the target parameter based on a modified temporary control setting; and

receive updated comparison information describing a comparison of the reference value and the adjusted actual value of the target parameter.

4. The system of claim 3, wherein the control circuit is further configured to receive an indication that the modified temporary control setting is stored in a non-volatile memory component included in the EHF communication circuit when the updated comparison information satisfies a target parameter tolerance level.

5. The system of claim 1, wherein the control circuit is further configured to receive an indication that the temporary control setting is stored in a non-volatile memory component included in the EHF communication circuit when the comparison information satisfies a target parameter tolerance level.

6. The system of claim 5, wherein the non-volatile memory component further comprises a plurality of fuses, and the temporary control setting is stored in the non-volatile memory component by selectively blowing one or more of the plurality of fuses.

7. The system of claim 1, wherein the control circuit is further configured to receive an indication that the temporary control setting associated with the target parameter is stored in a temporary storage register included in the EHF communication circuit.

8. The system of claim 1, wherein the target parameter represents a carrier frequency of an oscillator included in the EHF communication circuit, the carrier frequency being a frequency within the EHF band of radio frequencies.

9. The system of claim 1, wherein the target parameter represents a transmit power of an amplifier included in the EHF communication circuit.

10. The system of claim 1, wherein the target parameter represents a gain level of an amplifier included in the EHF communication circuit.

11. The system of claim 10, wherein the target parameter represents a gain level of an amplifier included in the EHF communication circuit.

12. The system of claim 10, wherein the amplifier is a low noise amplifier.
