for SENSORS
Surface acoustic wave (SAW) filters are manufactured by ITME for TV receivers (tables 1 and 2). We offer also: - SAW filters for cable TV modulators (table 3), - professional SAW filters (table 4), - SAW notch filters (table 5), - SAW, pseudo SAW (PSAW) and surface transverse wave (STW) components for sensors: delay line (table 6), resonators (table 7). ITME offers high quality SAW filters and components for sensors in the frequency range 20 500 MHz designed according to customers requirements. SAW FILTER CHARACTERISTICS :
 center frequency *
NOTES :
* Design of multiple passband filters with various passband shapes is possible.
** Filters can be designed according to phase or group delay specification.

WE OFFER THE FOLLOWING SERVICES CONCERNING SAW SENSORS :
 design and manufacturing of SAW delay lines and resonators on quartz and
lithium niobate and lithium tantalate substrates of any cut,  preparation copper phthalocyanine layers as the chemical interface for sensors.
OUR CUSTOMERS ARE ASKED TO SPECIFY:
 desired frequency response,
 max. insertion loss,
 source and load impedance,
 package type,
 temperature range of operation,
 max. permitted temperature coefficient of the frequency response,
 expected quantity.
