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.
● It can be manufactured for a wide frequency range from 40 to 170 MHz.
● Compact and light.
● Low insertion loss.
● Excellent temperature characteristics.
● SMA connector
