Abstract
A radio frequency (RF) device includes at least one RF chip, including a local oscillator configured to generate an RF signal. The RF device further includes an RF signal path coupling an output of the at least one RF chip and an input of the at least one RF chip, wherein the RF signal path is configured to feed the generated RF signal from the output of the at least one RF chip into the input of the at least one RF chip. The RF device further includes a processing unit coupled to the input of the at least one RF chip and configured to perform in a first mode at least one of testing, monitoring or calibrating the at least one RF chip based on the generated RF signal.
Claims24
A radio frequency (RF) device, comprising:
- at least one RF chip comprising a local oscillator configured to generate an RF signal;
- an RF signal path coupling an output of the at least one RF chip and an input of the at least one RF chip, wherein the RF signal path is configured to feed the RF signal from the output of the at least one RF chip into the input of the at least one RF chip;
- and
- a processing unit coupled to the input of the at least one RF chip and configured to perform, in a first mode, at least one of testing, monitoring, or calibrating the at least one RF chip based on the RF signal.
A radio frequency (RF) device, comprising:
- at least one RF chip comprising a transmit (TX) channel for a transmission of RF signals and a receive (RX) channel for a reception of the RF signals;
- and
- an RF signal path coupling an output of the TX channel and an input of the RX channel,
- wherein the RF signal path is configured to feed an RF signal from the output of the TX channel into the input of the RX channel.
A method for manufacturing a radio frequency (RF) device, the method comprising:
- arranging at least one RF chip comprising a local oscillator configured to generate an RF signal;
- coupling an output of the at least one RF chip and an input of the at least one RF chip by an RF signal path, wherein the RF signal path is configured to feed the RF signal from the output of the at least one RF chip into the input of the at least one RF chip;
- and
- coupling a processing unit to the input of the at least one RF chip, wherein the processing unit is configured to perform, in a first mode, at least one of testing, monitoring, or calibrating the at least one RF chip based on the RF signal.
