一種射頻放大器電路的制作方法

本申請涉及半導(dao)體應用,具(ju)體地(di),涉及一種射(she)頻放大器(qi)電路。


背景技術:

1、一種基于sic的(de)(de)fet器件具(ju)有(you)良好(hao)的(de)(de)直(zhi)流特性(xing)(xing)和(he)(he)射(she)頻(pin)特性(xing)(xing),該器件具(ju)有(you)高的(de)(de)工作電(dian)(dian)(dian)(dian)(dian)(dian)壓和(he)(he)高功(gong)率(lv)密度。這些特性(xing)(xing)在(zai)(zai)射(she)頻(pin)大(da)功(gong)率(lv)應用中具(ju)有(you)得天獨厚的(de)(de)優(you)越性(xing)(xing)。但是目前(qian)專利(專利號(hao):cn?115567017a)應用主要是在(zai)(zai)單(dan)路器件,如圖1所示。該電(dian)(dian)(dian)(dian)(dian)(dian)路是個典型的(de)(de)單(dan)管(guan)電(dian)(dian)(dian)(dian)(dian)(dian)路,該電(dian)(dian)(dian)(dian)(dian)(dian)路:包括sic場(chang)效(xiao)應管(guan)m1、靜態(tai)的(de)(de)柵極偏(pian)(pian)置(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路、靜態(tai)的(de)(de)漏(lou)極偏(pian)(pian)置(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路、射(she)頻(pin)輸入匹(pi)配電(dian)(dian)(dian)(dian)(dian)(dian)路、射(she)頻(pin)輸出匹(pi)配電(dian)(dian)(dian)(dian)(dian)(dian)路組成(cheng)。sic場(chang)效(xiao)應管(guan)m1通過柵極偏(pian)(pian)置(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路和(he)(he)漏(lou)極偏(pian)(pian)置(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路加電(dian)(dian)(dian)(dian)(dian)(dian)讓(rang)器件開啟工作。通過調節(jie)射(she)頻(pin)輸入匹(pi)配電(dian)(dian)(dian)(dian)(dian)(dian)路和(he)(he)射(she)頻(pin)輸出匹(pi)配電(dian)(dian)(dian)(dian)(dian)(dian)路讓(rang)器件工作在(zai)(zai)合適的(de)(de)狀(zhuang)態(tai),完成(cheng)對射(she)頻(pin)輸入信號(hao)的(de)(de)放大(da)功(gong)能(neng)。其中,fet器件的(de)(de)全稱是場(chang)效(xiao)應管(guan)(field?effecttransistor),sic是碳化硅。

2、上述(shu)現有專利(專利號:cn115567017a)中,是一個(ge)典(dian)型(xing)的單管(guan)功(gong)放(fang),射頻輸(shu)入信號通(tong)過(guo)一個(ge)sic場(chang)(chang)效(xiao)(xiao)應管(guan)m1進(jin)行放(fang)大,由(you)于sic場(chang)(chang)效(xiao)(xiao)應管(guan)m1放(fang)大能力受限于sic場(chang)(chang)效(xiao)(xiao)應管(guan)m1自(zi)身性能,所以一個(ge)sic場(chang)(chang)效(xiao)(xiao)應管(guan)m1放(fang)大能力肯(ken)定不(bu)如多個(ge)sic場(chang)(chang)效(xiao)(xiao)應管(guan)m1并(bing)列(lie)效(xiao)(xiao)果好(hao)。

3、但是圖1的電路實(shi)現(xian)多(duo)個sic場(chang)效應管m1并聯只(zhi)有兩種方式(shi):

4、第一種方式(shi):sic場效應管(guan)m1并聯,匹(pi)配電路(即射頻輸(shu)入匹(pi)配電路和射頻輸(shu)出匹(pi)配電路)不(bu)變;

5、第二種方式:sic場效應(ying)管m1和匹(pi)配(pei)電路(lu)(即射頻輸(shu)入匹(pi)配(pei)電路(lu)和射頻輸(shu)出匹(pi)配(pei)電路(lu))一(yi)起并(bing)聯(lian)。

6、針對(dui)第一種方(fang)式的情況,在應用中會增(zeng)加匹配難度,而且這樣的使用sic場效(xiao)應管m1很容易因(yin)為不平(ping)衡而造(zao)成自(zi)激(ji),增(zeng)加應用的風險。

7、對于第(di)二種方式的(de)(de)情況,在應用(yong)中會造成電(dian)路(lu)(lu)很復雜,而且電(dian)路(lu)(lu)級合路(lu)(lu)對單獨一路(lu)(lu)的(de)(de)端口阻抗要(yao)求較高(已經(jing)不是標準(zhun)的(de)(de)50ω),這樣(yang)單路(lu)(lu)調(diao)試難度增大(因(yin)為測試系統是標準(zhun)的(de)(de)50ω)。因(yin)此在現(xian)有(you)專利電(dian)路(lu)(lu)上要(yao)完(wan)成更(geng)大功率(lv)等級的(de)(de)應用(yong),就需要(yao)采用(yong)新的(de)(de)匹配電(dian)路(lu)(lu)。

8、在背景(jing)技術中(zhong)公開的(de)上述信(xin)息僅用于(yu)加(jia)強對本(ben)申請(qing)的(de)背景(jing)的(de)理解,因此其可(ke)能(neng)包含(han)沒(mei)有形成為本(ben)領域(yu)普通技術人員所(suo)知曉的(de)現有技術的(de)信(xin)息。
