load-matching network 中文意思是什麼
load-matching network
解釋
負載匹配網路-
( 2 ) the major circuit has been established, composed of rectifier 、 buck - chopper 、 push - pull inverter and matching network, which realizes high - power supersonic ac output. to achieve maximal output power, the pulse frequency modulation ( pfm ) has been applied to auto - adjustment of output frequency, which corresponds to the load ' s resonant frequency
( 2 )建立了超聲電源主電路,其中包括:整流、直流斬波、推挽逆變器和匹配網路等部分,實現了大功率超聲頻交流電的輸出,輸出頻率的脈頻調制( pfm )和輸出功率的脈寬調制( pwm ) 。 -
The resonance network is connected to the gate, then the output and input matching network is designed to satisfy the oscillation criteria. then harmonic balance method is used to analysize and optimize the output power and phase noise. to minimize the load pulling effect a buffer amplifier is designed to isolate the oscillator and the load
本文在場效應管fet柵極上加上諧振網路(諧振網路是通過cst模擬得到的,它是串聯反饋迴路,介質工作在te01模,對于其後的fet ,它又相當於一個帶阻濾波器) ,然後設計輸入輸出匹配電路,使電路結構滿足起振條件,之後繼續用諧波平衡法模擬和優化,使振蕩器輸出功率合適,相位噪聲很低。 -
Through the design the dc feed network, input matching network for the ne900175 gaas fet and analysis the stabilization, power gain, bandwidth of the power amplifier we get the power amplifier is stability, the power gain is 11. 967db and the bandwidth is 300mhz. microstrip antenna has a narrow bandwidth, in this design antenna ' s bandwidth is 100mhz. antenna is the not only the load of the power amplifier, but also as the filter connecting to the output of the power amplifier
E類功放的pae相對a類、 b類、 ab類的功率放大器類型而言比較高,在50 ? 70 。分析了e類功放的工作過程后,以ne900175的gaas場效應管作為e類功放電路的開關,進行了外圍電路的設計,包括直流偏置電路、輸入匹配網路的設計,功放的穩定性、帶寬、增益的分析。該功放增益最大達到11 . 4db ,帶寬為320mhz 。
