Patent ID: 8060007

Claim:
A radio frequency (RF) signal processing device comprising: (a) a receiver antenna for receiving a radio frequency signal having vertically polarized radiation and horizontally polarized radiation; (b) a first radio frequency detector included within said receiver antenna for receiving said radio frequency signal from said receiver antenna and then converting said radio frequency signal to an equivalent first high frequency optical signal; (c) a first fiber optic cable having one end connected to said first radio frequency detector; (d) a controller connected to an opposite end of said first fiber optic cable wherein said first fiber optic cable transmits said first high frequency optical signal from said first radio frequency detector to said controller for processing by said controller; (e) said controller phase shifting said first high frequency optical signal by ninety degrees, and then providing a high frequency electrical signal which includes a ninety degree phase shift; (f) an RF electrical cable having one end connected to said controller; (g) a transmitter antenna connected to an opposite end of said RF electrical cable wherein said RF electrical cable transmits said high frequency electrical signal including said ninety degree phase shift from said controller to said transmitter antenna; (h) a second radio frequency detector included within said transmitter antenna for monitoring said high frequency electrical signal from said controller and then converting said high frequency electrical signal to a second high frequency optical signal which includes amplitude and phase information for said high frequency electrical signal; (i) a second fiber optic cable having one end connected to said second radio frequency detector and an opposite end connected to said controller wherein said second fiber optic cable transmits said second high frequency optical signal including said amplitude and phase information from said second radio frequency detector to said controller; and (j) said controller responsive to said second high frequency optical signal, making adjustments to said high frequency electrical signal to insure that there is said ninety degree phase shift between said radio frequency signal received by said receiver antenna and an equivalent radio frequency signal to be transmitted by said transmitter antenna.
