Topology for dual-band LNA design

hi

can any one recomend me topology for daul band lna .which will operate at VHF (174-240)and L-band(1450-1490).same circuit will be used for two frequencies.

thanks in advance

Added after 1 minutes:

and two frequencies are operated seperately

You can use a wideband LNA (or a MMIC) that cover from 174MHz to 1490MHz, but with some bad consequences (it will amplify also un-wanted frequencies). If you already have band-pass filters for each band after the LNA, would be better.

thank you very much for your reply and your idea

my main aim is to decrease chip area and power dissippation.I think that one is not suitable for me as u told i may get some troubles with wideband amplifier.

thanks
