Product Description

Product Description

The surface-acoustic-wave (SAW) resonator is the surface-wave equivalent of the crystal resonator now used extensively for stable frequency sources and filters. High-Q operation above 30 MHz, ruggedness, and small size characterize these devices.

The main advantages of SAW resonators are:

• High frequency accuracy
• Low temperature dependence
• Compact design

The high frequency SAW resonators offer high quality and temperature stability of the frequency.

We offer a wide range of 1-port and 2-port SAW resonators for use in all frequency ranges. and we can develop and manufacture SAW resonators for all frequency ranges up to 3 GHz according to customer requirements
