Telewave Crystal Filters provide an extremely narrow bandpass for a single frequency, to protect a receiver from nearby transmitters and adjacent channel interference. This bandpass is much sharper than a typical high "Q" cavity filter. The combination of a crystal filter and a Telewave TLA or TGA series preamplifier can often rescue a receiver that has been impacted by an new adjacent transmitter, or allow implementation of a system with insufficient available frequency spacing.
