SAW Filter

SAW filters are an important component of modern communication systems. This is due to the combination of very good electrical properties with their small dimensions. In addition, SAW filters have more stable properties against external influences compared to their LC element and piezoceramic counterparts.

The main advantages of SAW filters are:

low insertion loss
high blocking attenuation
high power compatibility
small size
independence of frequency response (FFR) from amplitude frequency response (AFR)
high rectangularity of AFR
good temperature stability

We manufacture SAW filters in complete production runs from 30 MHz to 3 GHz for up to 30 dBm transmit power and a wide range of wireless applications. Below you will find our list of standard components.

You have not found the right component? We develop and manufacture SAW filters for all frequency ranges up to 3 GHz according to customer requirements. Please contact us!

SAW sensors and SAW IDENT components

Here you will find SAW sensor components and SAW IDENT components for use in your sensor modules for the following measured variables:

Temperatures from -40°C to +350°C
Identification (RFID) from -40°C to +350°C

SAW sensors are suitable wherever conventional sensor systems come to their limits - be it due to high temperatures, fast movement or because no power supply is possible. SAW sensors are characterized by the fact that they deliver the highest precision even under difficult environmental conditions. These include not only high temperatures but also electromagnetic fields in electric motors, ionizing radiation, high movement speeds and mechanical loads.

We also develop and manufacture SAW sensors for you according to customer requirements. Please contact us!
