SAW filterS for AMr ApplicAtion
SAW filters for AMR Application
the iDt family of SAW filters feature extremely low loss, high frequency selectivity and low cost,
all critical to successful AMr equipment design.
Description
Automated Meter Reading (AMR) is an emerging market worldwide. Using two way communications to
signal and extract usage data from remote locations, AMR systems require the use of SAW filters to eliminate
potential signal interference. Typical AMR applications are used to monitor usage of electricity, water and
gas. IDT has developed low insertion loss SAW filters that are ideally suited for providing signal integrity
and rejecting interference. Several popular frequencies are available including 915 MHz, 868 MHz and
433 MHz.
SAW features:
High reliability
Insensitive to shock and vibration
Low insertion loss or high performance
Frequency stable over temperature
Flat passband
Uniform group delay
Small size
Low cost
Standard surface mount
RoHS
