With a 1 mH choke it works from 60 KHZ to more than 1.8 GHZ. With a smaller inductance works up to 2.7 GHZ! More than 17 dB gain, 1 W power output! Highly linear! No harmonics...We need to test more...I will report soon.
NEW! RG-405 pigtails with SMA plugs, better and more durable than cheap RG-316...even for everyday lab use. Not much more expensive!

@RFAmirhosein Yes, this is correct if you use this filter between an antenna and a receiver. But if placed after a multicoupler or LNA then the noise figure is not affected.
