COPLANAR WAVEGUIDE AMPLIFIER |
摘要 |
An amplifier including an amplifying transistor flip-mounted on a coplanar waveguide pattern. Elements of stability and/or matching circuits are provided at least in part under the flip-mounted transistor to facilitate compact design and to improve component performance. A serial resistor-shunt inductor pair is provided with the resistor coupled proximate the transistor input and/or output and preferably configured within the CPW center conductor to provided more consistent component values. Embodiments of the present invention include a two-stage amplifier having a transmission segment formed between the two stages which serves to rotate the output impedance of the first stage toward a low noise match with the second stage and to rotate the input impedance of the second stage toward a high gain match with the first stage. The transmission segment may include a capacitive element for providing series capacitance and DC blocking. Adjustable impedance matching means are also taught. |
