壓控振蕩器
壓控振蕩器 (VCO) 是一種以電壓輸入來用來控制振蕩頻率的電子振蕩電路設(shè)計。其振蕩的頻率或重復的比例會隨著直流電壓的不同而改變,這個特性可以用來將調(diào)變訊號當做壓控振蕩器的輸入而產(chǎn)生不同的調(diào)變訊號。
產(chǎn)品特點
專為通信系統(tǒng)的上下變頻器而開發(fā)的寬帶壓控振蕩器。
可提供8V電源電壓下工作的產(chǎn)品,但輸出功率會降低4dB左右。
輸出阻抗50Ω,為了改善與混頻器之間的匹配,建議用戶在輸出端與混頻器LO端接一只2db固定電阻衰減器。
以上型號僅為標準產(chǎn)品,根據(jù)用戶不同需求,可提供特殊指標要求的產(chǎn)品。
