Basic view of our products

crystals Quartz crystals
We offer crystal units (resonators) in frequency range from 1 up to 200 MHz in all types of standard metal cases, with possibility of terminals shaping for SMD assembly. Some of the crystal units are also designed in ceramic SMD cases.
According to customer agreement, the crystal units are possible to be delivered in wound carrier tape reels, which is suitable for automatic assembly.
filters Crystal filters
We offer many types of crystal and monolithic filters, with standard or custom parameters. The filters are encapsulated into standard types of metal cases. Special customer requested cases are also possible.
Our newest production technology enables the production of 4-poles filters in one ceramic case SMD 7×5 mm. Similar design is used for 2-poles filters according to customer specification.
wafers, blanks Wafers, substrates for SAW devices
Thin wafers are starting product for production of devices on the base of SAW. We produce the wafers with diameter 3“ (76.2 mm) and 4“ (100.0 mm), with thicknesses from 0.25 to 1 mm and with fine-lapped or polished surface.
Wafers are produced from synthetic quartz with specified quality or some other piezo-electric materials.
oscilators Crystal oscillators
Our standard offer containts high stable temperatur compensated crystal oscillators (TCXO) in the range from 5 up to 24 MHz. We also offer voltage controled temperature compensated crystal oscillators (VCTCXO).

Thanks to our good contacts with manufacturers and suppliers from around the world we can offer more products. These include low-frequency crystals, SAW filters and others. Contact us with your inquiry.
