چکیده
In this paper, a novel power amplifier (PA) is proposed. An asymmetrical branch-line coupler exploited as the output matching circuits of proposed PA. Meanwhile, by setting impedance conditions with trade-off in desired pass-band appropriately, and combination can be realized single circuit. A brief analysis presented. Compared traditional high-power PAs design method, method meet requirement miniaturization. To prove validity PA works at 2GHz designed, fabricated measured using 10-W gallium nitride (GaN) transistor (CGH40010F). The results show that saturated 42.8-45.2dBm power-added efficiency 52.0-62.6% achieved gain between 7.9 10.1dB.

Dual-Band Branch Line Coupler using CRLH Transmission Lines
A branch-line coupler (BLC) working at two arbitrary frequencies using CRLH transmission lines (TLs) is presented. It is demonstrated that the two operating frequencies can be obtained by tuning the phase slope of the different line sections. A prototype is demonstrated using only microstrip technology.
متن کاملDesign of Bandpass filter Using Branch-line Directional Coupler
This paper presents the design of a bandpass filter using directional coupler. The concept of transerval filters is applied to design of microwave filters. The directional coupler is used as a transversal filtering element. This is achieved by loading the coupled ports of the filter with open-circuited stubs. The dependence of filter characteristics on the stub lengths and impedances is demonst...
متن کاملCompact Slow-Wave Branch-Line Coupler Using Crossing Bond Wires
This paper proposes a compact and miniaturized branch-line coupler using a crossing bond wire structured slow-wave branch line (CBWSWB). The proposed coupler achieves a size reduction of 82% compared with a conventional implementation. Measured S11, S21, S31 and S41 of the proposed coupler are better than −24, −3.7, −3.7 and −28 dB at 3GHz, respectively. Furthermore, the phase difference betwee...
متن کاملCompact Branch-line Coupler for Harmonic Suppression
This paper presents the modified design that can reject harmonic components in the branch-line coupler. After adding open stubs at the center of branch lines of the traditional design, their new network parameters can be found in order to maintain the conventional function at an operating frequency and suppress its harmonic terms chosen. Experimental results show the second and third harmonic s...
