Other Parts Discussed in Thread: TRF370417
TRF3705 IQ调制器规格书上写明了其1-dB input frequency bandwidth是1000MHz,那是不是此IQ调制器输出RF信号带宽最大可达2000MHz?

TRF3705 和 TRF370417 是复杂的正交调制器,可以支持 0Hz 中心中频(即直接零中频上变频)。
Typically, with the direct upconversion with message signal m(t) and Hilbert transform mh(t) of bandwidth B, your final upconverted signal will have 2*B of total bandwidth.以下是大多数 I/Q 调制器的通用公式。
