AF10-12D Datasheet, PDF (1/1 Pages) NIHON DEMPA KOGYO – Antenna Filter

Crystal Filter
Antenna Filter
n 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.
