rf range bandpass filter ( LC )

[lathoi sisen]

can any stalwart help me to design bandpass filter in range 300-500 MHz with less IL ,i used AWR and genesys but not fruitfull results in implementing practically.::???:

What are your specifications ??
Midband Insertion Loss, Out-of-band Rejection@Offset frequency, Lumped or Distributed, Implementing Space ( small or no limit)..

Hey bigBoss you are a real Boss of Electronics. How do you know what values for inductors and capacitor you must use?
Is it single wire or microstip line in the circuit?

thank you for replies. actually iam using coilcraft 603 or 402 size components and space is limited ,whole pass band IL should be constant value of less than -2dB,at middle and at offset edges.

my specification are: cutt-off frequency 325MHz-470MHz
IL -1.5dB max, RL -20dB
lumped elements of coilcraft components 603 or 402 size
n=5 or n=6. the design should be implemented practically at receiving fro nt of receiver.
