Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
An amplifier for radio frequency signals comprising: (a) a first and a second radial line, each having an E-plane bend formed in the peripheral portion thereof and centrally disposed means for connecting a signal to be amplified to the first radial line and an amplified signal to a load; and (b) a plurality of like amplifier channels radially disposed between the first and the second radial line, each one of such amplifier channels being coupled to the first and the second radial lines adjacent to the E-plane bend in such lines and incorporating a solid state diode as the active element.
Claim 2
Dependent Claim
101 words
An amplifier for radio frequency signals comprising: (a) a first and a second radial line, each having an E-plane bend formed in the peripheral portion thereof and centrally disposed means for connecting a signal to be amplified to the first radial line and an amplified signal to a load; and (b) a plurality of like amplifier channels radially disposed between the first and the second radial line, each one of such amplifier channels being coupled to the first and the second radial lines adjacent to the E-plane bend in such lines and incorporating a solid state diode as the active element.
Claim 3
Dependent Claim
66 words
The amplifier as in claim 1 wherein each amplifier channel comprises: (a) stripline circuitry having a first and a second flared notched radiators formed therein, the first one of such radiators being coupled to the first radial line and the second one of such radiators being coupled to the second radial line; and (b) and IMPATT diode and a first circulator coupled to the stripline circuitry.
Claim 4
Dependent Claim
87 words
Tha amplifier as in claim 2 having, additionally: (a) a second circulator disposed in the stripline circuitry between the first circulator and the second flared notch radiator, such second circulator being effective to permit radio frequency energy to flow from the first circulator to the second flared notch radiator and to direct radio frequency energy flowing from the second flared notch radiator to a path separated from the path between the first circulator and the flared notch radiator; and (b) a dissipative load disposed in the path.
