Dear all,
I am Vikash Gupta from India.
I am designing a duplexer having low frequency:230 MHz, High gfreuqency: 234
MHz.
I am using coil with 8 no. of turns and 22 PF capacitor.
I have to get Insertion loss <1.2 on both low and high sides.
But I have a problem in getting this.
I have got Rejection of more than 80 dB and Return loss of better than 20 dB
on both sides.
Please give me suggestion what I have to do?
thanks in advance.
Vikash
