VCO sweeping

by s13200670r on Sat May 06, 2017 11:19 am

Hi
I use ROS-2500+ for my jammer design. it's output power is 7 dBm. But when I sweep the VCO with an app. 50k or 100k or 1k tuning triangular voltage it's output power reduces about 40 dB (-30 dBm)! it is very bad for me ... I want to have 40 dBm output power so I should use at least three stage PA (to achieve 60 or 70 dB gain) and it is not efficient for me...
what should I do? please help me!!!!!!!!!!!!
