- RF●Microwave●Dielectric Filter(GVF series)
GOVA GVF Series dielectric ceramic filter are specially designed for RF applications, based on the advanced microwave ceramic materials and advanced design concept, we now can provide the filters with smaller size, lower IL, sharp steep attenuation transition from pass to stop band and good attenuation performance on out band frequency. With the special RF application requirements, we developed the RF ceramic materials, special metallization pasta, and special process control, focal on the improvement on Q value, Tcc and make sure the filter with lower IL and lower ripples which are critical parameters for RF applications
● Features
- 30 ppm temperature coefficient, suitable for the RF stable performance expectations
- High Q value @ RF frequency range
- Applicable for 800MHz-6GHz
- Better power transfer abilities
- Good IL for selected band and good attenuation level for outside selected band
- Sharp steep curve and lower ripple in pass band
- High stability and excellent reliabilities since the component composed by ceramic material and metallization structure.
- Stable performance @ RF application, provide very lower noise figure in the RF applications
- Completely compatible with SMD process
- Compatible with lead-free soldering process
- RoHS Compliant
● Application
