122.400MHz crystal filter with only 3dB insertion loss

by donpedro

MSC now offers the FTR80361, a 122.400 MHz fundamental mode monolithic crystal filter, from Precision Devices (PDI). The FTR80361 filter features insertion loss of 3dB maximum, spurious response of 70dB minimum and increased bandwidth of up to 200kHz. The device is provided with a terminating impedance (input/output) of 50ohms. Pass bandwidth is a minimum of ±35kHz at 3dB, with passband ripple 1.0dB maximum. Stop bandwidth is a maximum of ±768kHz at 70dB and ±350kHz at 60dB.
To save board space in compact applications, this new crystal filter is housed in a small 25.1mm × 10.0mm × 15.00mm package. A new SMD version is scheduled to be available in Fall 2012. The wide operating temperature range of -40°C to +85°C makes the FTR80361 suitable for use in harsh industrial environments.
