Patent ID: 7065326

Claim:
A millimeter wave communications system comprising: A) a first millimeter wave transceiver system located at a first site capable of transmitting and receiving to and from a second site through atmosphere digital information at frequencies greater than 70 GHz and at data rates of about 1.25 Gbps or greater, said first transceiver comprising: 1) at least one antenna producing a beam having a half-power beam width of about 2 degrees or less, and 2) a high performance modulator circuit comprising: a) a diode defining a diode capacitance and a lead inductance and b) a tuning means, wherein in an “off” state, the tuning means, diode capacitance and lead inductance all combine to form a resonant LC circuit which, when tuned, presents a radio frequency short across a transmission line in said first transceiver stopping transmission at a transmission frequency in excess of 70 GHz and wherein in an “on” state, the tuning means, diode capacitance and lead inductance all combine to form a resonant LC circuit which, when out of tune, removes the radio frequency short across the transmission line permitting transmission at a transmission frequency in excess of 70 GHz; and B) a second millimeter wave transceiver system located at said second site capable of transmitting and receiving to and from said first site digital information at frequencies greater than 70 GHz and at data rates of about 1.25 Gbps or greater, said second transceiver comprising: 1) at least one antenna producing a beam having a half-power beam width of about 2 degrees or less and 2) a high performance modulator circuit comprising: a) a diode defining a diode capacitance and a lead inductance and b) a tuning means, wherein in an “off” state, the tuning means, diode capacitance and lead inductance all combine to form a resonant LC circuit which, when tuned, presents a radio frequencv short across a transmission line in said first transceiver stopping transmission at a transmission frequency in excess of 70 GHz and wherein in an “on ” state, the tuning means, diode capacitance and lead inductance all combine to form a resonant LC circuit which, when out of tune, removes the radio frequency short across the transmission line permitting transmission at a transmission frequency in excess of 70 GHz.
