SAW FILTERS and COMPONENTS
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 *
* 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,
temperature range of operation,
max. permitted temperature coefficient of the frequency response,

Andrewes and the Caroline Divines’ Teaching on the Blessed Paper for the Ecumenical Society of the Blessed Virgin Mary. November, 2000. Neither are we unmindful to bless Thee, for the most holy, pure, highly blessed, the Mother of God, Mary the eternal Virgin, with all the Saints . So prayed Lancelot Andrewes in the Orthodox tradition frequently. Andrewes who ended his life as bishop of W
It is a paradox of the work of Artificial Intelligence that in order to grant con-sciousness to machines, the engineers first labour to subtract it from humans, asthey work to foist upon philosophers a caricature of consciousness in the digitalswitches of weights and gates in neural nets. As the caricature goes into publiccirculation with the help of the media, it becomes an acceptable counter
