品佳集團(tuán)積極推廣 NXP高效能超低噪聲的微波晶體管
品佳集團(tuán)近期積極推廣NXP高效能超低噪聲的微波晶體管,高頻應(yīng)用(20GHz以下)的NPN微波晶體管BFU725F 可提供極佳的高切換頻率、高增益和低噪聲等組合性能。藉由其超低的噪聲系數(shù),非常適用于敏感度高的 RF module 及 High performance mobile phones;此外,其高切換頻率的特色可用作 10GHz ~ 30GHz 之微波應(yīng)用如衛(wèi)星電視接收器及汽車防撞雷達(dá)的解決方案。
BFU725F 采用了創(chuàng)新的硅鍺碳 (SiGe:C) BiCMOS制程–QUBiC4X,這是專門為符合現(xiàn)實生活中的高頻應(yīng)用要求所設(shè)計的,可提供優(yōu)越的高功率增益及動態(tài)范圍組合性能,這個晶體管可謂將砷化鎵 (GaAs) 的性能及硅鍺碳的可靠性結(jié)為一體,但不需像使用砷化鎵組件時還要再增加負(fù)偏置電壓 (negative biasing voltages)的設(shè)計,所以在產(chǎn)品應(yīng)用上更能為客戶帶來成本效益,此產(chǎn)品目前巳有樣品可提供申請,預(yù)計于2007年第三季可量產(chǎn)供貨。
