Hello sirs, Please give me a solution for below problem. Without RF i/p my mixer gives IF output with LO driven by circuit in pcb which is not intended. With LO driven by SIGGEN it is functioning as expected. But my PCB LO circuit also has output clean spectrum. When I feed that to mixer there my pbm arises. My LO is 73 to 100MHz and IF is 70MHz -- Regards, Muthukumar V. G., Dy.Engineer, D & E MCE, Bharat Electronics Ltd, Jalahalli, Bangalore - 13. Every 3000 Sheets of paper costs us a tree..
