    How to design this LNA? [Gain: 8 dB, NF: <1dB, IIP3: 10dB

    Re: how to design this lna? Thanks for your replies! activewei:In fact I add the resistor network at the output of the amplifier, so that the NF just get a little worse. dhlee:I haven't enough points to download the file.Can you send it to my emails:liaodongyuan@hotmail.com or...

    How to design this LNA? [Gain: 8 dB, NF: <1dB, IIP3: 10dB

    atf54143 amplife f:1850-1910MHz Gain:8dB NF:<1dB IIP3:10dBm a single-stage balanced amplifier(I use two ATF54143) To meet the low gain,I add a Pi Resistor network,but the NF become worse(about 1.2dB).Can you help me?

    help: power divider (1 vs 5) for 500W power at 3 GHz

    you can use broad-side couple stripline for less insert loss.
