Precision Devices Inc. has announced the 
FTR80220, its latest 124.800MHz fundamental crystal filter. Made in the USA, the FTR80220 crystal filter is targeted at a broad range of RF applications. The company reports that the FTR80220 filter offers better selectability and lower insertion loss in a smaller package, compared to competitors.
The FTR80220 crystal filter operates on the fundamental mode, with insertion loss improved to 3dB maximum, spurious response now 70dB minimum and increased bandwidths of up to 200kHz. The device is provided with a terminating impedance (input/output) of 50 Ohms.
Pass bandwidth is a minimum of ±35kHz at 3dB, with passband ripple 1.0dB maximum. Stop bandwidth is a maximum of ±350kHz at 60dB and ±768kHz at 70dB.
The new filter is supplied in a 25.1mm x 10.0mm x 15.00mm package. The FTR80220 crystal filter has a wide operating temperature range of -45°C to +85°C, making it suitable for industrial applications in harsh conditions.
Availability
The FTR80220 crystal filter is available immediately from Precision Devices and through global distribution partners.
