Abstract
An on-chip power sensor and a millimeter-wave communication device (e.g. transmitter or transceiver) on a chip including the on-chip power sensor are described. The millimeter-wave communication device can also include a coupler disposed on a transmit path, the coupler being configured to receive a transmit signal and to provide the transmit signal to an antenna connection (e.g. pad). The on-chip power sensor can be configured to receive a coupled portion of the transmit signal from the coupler, and measure a transmit power of the transmit signal based on the coupled portion of the transmit signal.
Claims20
A millimeter-wave communication device on a chip, comprising:
- a coupler disposed on a transmit path, the coupler being configured to receive a transmit signal and to provide the transmit signal to an antenna connection;
- and
- an on-chip power sensor configured to:
- receive a coupled portion of the transmit signal from the coupler, and
- measure a transmit power of the transmit signal based on the coupled portion of the transmit signal.
A millimeter-wave communication device comprising:
- a coupler disposed on a transmit path, the coupler being configured to receive a transmit signal via the transmit path, generate a coupled portion of the transmit signal, and provide the transmit signal to an antenna connection of the transmit path;
- a power estimator configured to estimate the transmit power of the transmit signal based on the coupled portion of the transmit signal;
- a first on-chip power sensor configured to measure the transmit power of the transmit signal based on the coupled portion of the transmit signal;
- and
- second on-chip power sensor that is configured to measure a radio frequency (RF) power of the received signal.
