| 330005000 | WITH SOLID ELEMENT WAVE PROPAGATING AMPLIFYING DEVICE | 6 |
| 20080315944 | SPATIALLY-FED HIGH POWER AMPLIFIER WITH SHAPED REFLECTORS - A spatially-fed high-power amplifier comprises one or more shaped reflectors to reflect an initial wavefront, and an active array amplifier to amplify the reflected wavefront to generate a high-power planar wavefront. The shaped reflectors provide the reflected wavefront with substantially uniform amplitude when incident on the active array amplifier. The initial wavefront may be a substantially spherical wavefront, and the shaped reflectors may compensate for any amplitude taper of the initial wavefront to provide the reflected wavefront with substantially uniform amplitude components for incident on the active array amplifier. In some embodiments, the shaped reflectors may also contour the illumination to fit the shape of the active array amplifier to help minimize spillover. | 12-25-2008 |

The circuit includes a circuit network unit formed of a direct-current feeding circuit and a microwave power signal circuit. The direct-current feeding circuit comprises a high-electron-mobility transistor (HEMT) drain power-up bonding point, a corresponding line, a feeding end of a tail-level HEMT transistor core, a first Metal-insulator-Metal (MIM) capacitor, a first micro-strip inductor, symmetrical branch micro-strips, a second MIM capacitors. The microwave power signal circuit comprises a signal end of the tail-level HEMI transistor core, two third MIM capacitors, other electrode of the second MIM capacitors, a ground micro-strip inductors, a second micro-strip inductors, a third micro-strip inductor, a fourth MIM capacitor. | 05-07-2015 |
| 20160065154 | TRAVELLING WAVE AMPLIFIER (TWA) FOR DRIVING OPTICAL MODULATOR - A travelling wave amplifier (TWA) with a widened frequency bandwidth is disclosed. The TWA include input transmission lines, amplifier units connected in parallel between the input terminal and the out terminal of the TWA. Each of the amplifier units configures an emitter follower in the front end thereof and an amplifying section. A feature of the TWA is that compensation units that compensates the high frequency performance of the TWA are implemented in the input transmission lines and/or integrated with the amplifier units. | 03-03-2016 |
