Abstract

An electromagnetic Extremely High Frequency (EHF) communication chip includes one or more local oscillator circuits, a transducer circuit and at least one of a modulator or a demodulator coupled to the transducer circuit. Each of the local oscillator circuits may have a local oscillator and configured collectively to generate first and second carrier signals having respective first and second EHF frequencies. The first EHF frequency may be different than the second EHF frequency. The transducer circuit may have a first transducer for transmitting and receiving EHF communication signals. The modulator may be coupled to the local oscillator circuits for modulating the first carrier signal or the second carrier signal with a first transmit base data signal. The demodulator may be for demodulating the first carrier signal or the second carrier signal to produce a first receive base data signal.

Claims

1. An electromagnetic Extremely High Frequency (EHF) communication chip comprising:

a transducer circuit having at least one transducer;

first and second modulators coupled to the transducer circuit;

first and second demodulators coupled to the transducer circuit;

a first data channel for carrying a first base data signal;

a second data channel for carrying a second base data signal;

a cross-point switch coupled to the first and second modulators, the first and second demodulators, the first data channel, and the second data channel, the cross-point switch being configured to selectively connect one or both of the first and second data channels to one or more of the modulators and demodulators; and

a controller circuit coupled to the cross-point switch, wherein the controller circuit is configured to;

detect communication information from at least one of the first base data signal and the second base data signal, and

control, in response to the detected communication information, switching of the cross-point switch in selectively connecting one or both of the first and second data channels to the one or more of the modulators and demodulators.

2. The electromagnetic EHF communication chip of claim 1, wherein the controller circuit controls the switching of the cross-point switch based on the detected communication information indicating which of the demodulators is receiving an EHF communication signal corresponding to a respective alignment of one of the at least one transducer of the EHF communication chip and an external transducer of an external device.

3. The electromagnetic EHF communication chip of claim 1, wherein each data channel includes a corresponding transmit data line and a corresponding receive data line, the cross-point switch being further configured to selectively connect one or both of the modulators to one or both of the transmit data lines, and to selectively connect one or both demodulators to or both of the receive data lines.

4. The electromagnetic EHF communication chip of claim 1, further comprising:

at least one oscillator circuit to generate at least one RF carrier signal, the first and second modulators and the first and second demodulators coupled to the at least one oscillator circuit.

5. The electromagnetic EHF communication chip of claim 1, wherein the controller circuit is further configured to generate one or more signals to control operation of one or more components of the electromagnetic EHF communication chip in addition to the cross-point switch, and communicate associated information with an external device.

6. The electromagnetic EHF communication chip of claim 5, wherein the controller circuit is configured to communicate with the external device via a supply voltage lead.

7. The electromagnetic EHF communication chip of claim 5, wherein the controller circuit controls the operation of the one or more components in response to a sensed change in at least one operating parameter of the EHF communication chip.
