Verifying RF Device Performance with a Blocking Test

The increasing density of devices, machines, systems and vehicles using wireless connectivity solutions can pose a great challenge for a new Wi-Fi module due to the presence of interfering signals. A wireless receiver’s ability to receive a wanted signal in the presence of an interfering signal is described by blocking characteristics. These characteristics are also known as desensitization performance since they have a considerable impact on receiver sensitivity. Blocking tests are therefore crucial for determining whether a receiver works as it should.
