thank you for ur replay DDavid and biff44,,
ya i do need to simulate build and test ...using the microstrip ,, that's y , i want to use the disrtibuted components ..
the bandwidth is 90 Mhz,,
in my lumped components circuit ,,i designed it using the ATF-34143 with 2 inductors for the simultanoues input matching impedance (ZM1) and simultanoues output matching impedance
also in each side i added the component( TLIN ) for defining the angle 90 degree and impdeance. etc..
if u didnt get my point i'll print scrn for the circuit diagram .. help me plz i dunno how to start with this type of circuit
