VHF BIRD RF Low Pass Filter bandwidth Measurement using tracking generator & technical discussion.

Here we look at the Bird VHF Low Pass Filter (LPF) by making bandwidth measurements on the IFR 2968 radio test set tracking generator, we look at the 3db points, & its rejection specification at higher frequencies, i explain what these are used in a typical operational aspect, & we discuss the use in different applications with radio transceivers with high power RF Amplifiers & their harmonic content. So sit back & enjoy the ride.
