(canceled)
A microwave energy delivery device comprising:
- a housing;
- a microwave antenna coupled to the housing and configured to transmit a microwave energy signal;
- a remote RF sensor disposed within the housing and coupled to the microwave antenna, the remote RF sensor including:
- a remote directional coupler, a first mixer, and a second mixer, the remote directional coupler configured to provide a forward power measurement signal to the first mixer and a reverse power measurement signal to the second mixer;
- and
- a remote sensing interface configured to transmit at least one of the forward power measurement signal or the reverse power measurement signal to a microwave generator.
