1. An antenna module, comprising:
- an antenna configured to receive an electromagnetic signal in a signal path, the antenna being electrically coupled to a circuit connector;
an amplifier configured to amplify the received electromagnetic signal, and to provide the amplified signal at a first node;
a filter configured to receive the amplified signal from the first node, and to provide a filtered signal output therefrom; and
a noise canceller and a detector integrated in the signal path at the first node, wherein the amplifier, the filter, the noise canceller, and the detector are electrically coupled to the circuit connector.
