Input Interface
AC coupled (External blocking capacitor is required)
Output Interface
AC coupled (External Bias-T is required for VD)
*1 Output Amplitude can be controlled by VC1 and VD voltage. We recommend to control output amplitude by
VD voltage. ( VD is more effective than VC1. )
*2 VD is supplied at Output Port using External Bias-T.
