Document Type and Number:
Japanese Patent JP7002257
Kind Code:
B2
Abstract:
Receivers and methods of testing are described. A receiver includes a plurality of receiver channels, each including an amplifier for receiving a signal from an antenna and a mixer downstream of the amplifier. A test signal generating circuit is configured to generate test signals. A signal path connects the test signal generating circuit and each receiver channel and couples to each receiver channel at a coupling between the amplifier and a mixer. A test signal from the test signal generating circuit is injectable to the parts of the receiver channel downstream of the amplifier. The test signal may alternatively be injected into the entire receiver channel. The receivers and methods may be used in wireless systems, such as radar systems and radio systems.
