Shape memory alloy receiver

Abstract

In one embodiment, a frequency agile receiver is provided that includes an antenna: a first diode having its anode coupled to ground through a first conductor; a second diode having its anode coupled to the cathode of the first diode through a second conductor, the antenna coupling to the second conductor, the second diode having its cathode coupled to an output node through a third conductor, wherein at least one of the first, second, and third conductors comprises a shape memory alloy conductor; and a tuning circuit adapted to drive a bias current into the shape memory alloy conductor.

1 . A frequency agile receiver, comprising:
 an antenna;   a first diode having its anode coupled to ground, through a first conductor; a second diode having its anode coupled to the cathode of the first diode through a second conductor, the antenna coupling to the second conductor, the second diode having its cathode coupled to an output node though a third conductor, wherein at least one of the first, second, and third conductors comprises a shape memory alloy conductor; and   a tuning circuit adapted to drive a bias current into the shape memory alloy conductor.   
     
     
         2 . The frequency agile receiver of  claim 1 , wherein each of the first, second, and third conductors comprises a shape memory alloy conductor. 
     
     
         3 . The frequency agile receiver of  claim 2 , wherein each shape memory alloy conductor comprises Nitinol.
