Features
This compact crystal filter for small antennas has been developed to remove
interference caused by nonlinearity of a receiver and has low insertion loss across a
wide frequency range.
l
It can be manufactured for a wide frequency range from 40 to 280 MHz.
l
Compact and light.
l
Low insertion loss.
l
Excellent temperature characteristics.
