Microwave/Millimeter Wave Amplifier With Rf Feedback
US Patent:
4525680, Jun 25, 1985
Filed:
Apr 22, 1983
Appl. No.:
6/488427
Inventors:
Jing-Jong Pan - Melbourne FL
John B. Wilson - Palm Bay FL
John B. Wilson - Palm Bay FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H03F 3193, H03F 360
US Classification:
330277
Abstract:
An RF MESFET amplifier having a feedback resistor further incorporates two sets of quarter wavelength low impedance pads and quarter wavelength high impedance lines in the resistor feedback path. These RF impedance elements prevent RF feedback as well as thermal noise generated by the feedback resistor from being coupled to the input. Moreover, they effectively isolate RF interaction between the drain and gate of the MESFET; as a result, the amplifier has excellent stability. The low impedance quarter wavelength pads serve as an RF bypass (to ground), while the high impedance quarter wavelength lines provide high attenuation near frequencies at the given wavelength. Consequently, thermal noise generated by the feedback resistor will be bypassed to ground and will not leak into the gate. The value of the feedback resistor can be selected and optimized to obtain the desired VSWR, bandwidth and gain flatness.
