Hello
I am designing a matching network to transform a 50Ω source to a complex impedance 300-j450Ω. I want a BW of 100MHz. My center freq is 1.42GHz. I use the formula Q=f0/BW, to find the required Q for my matching network. It is calculated to be 14.2. But if i design it this way i cannot achieve the BW i want. I need to design for Q=3 to achieve the 100MHz BW. Why the formula doesn't stand? Any ideas. Am i getting something wrong?
Thanx in advance
George
