Precision Devices has announced the FTR80220, its latest 124.800MHz fundamental crystal filter. The crystal filter is targeted at a broad range of RF applications. The filter is claimed to offer good selectability and low insertion loss in a small package.
According to the company, the filter enhances the performance by operating on the fundamental mode, with insertion loss optimised to 3dB maximum, spurious response of 70dB minimum and bandwidths of up to 200kHz. The filter is provided with a terminating impedance of 50Ω.
Pass bandwidth is a minimum of ±35kHz at 3dB, with passband ripple 1dB maximum. Stop bandwidth is a maximum of ±350kHz at 60dB and ±768kHz at 70dB. The filter is available in a 25.1x10x15mm package. The crystal filter operates from -45 to +85°C, making it suitable for industrial applications in harsh conditions.
