CRYSTAL FILTERS
This is a compact and low insertion loss crystal filter for
small antennas for removing interference stemming from
nonlinearity of the receiver.
■Antenna filters
■Features
8Can be manufactured for a wide range of frequencies
(40~280 MHz)
8Compactness and light weight
8Ripple and insertion loss are especially low
8Outstanding temperature characterisics
