The Joymax DRF-SJ6525A is a band-pass DR (Dielectric Resonator) filter designed for use in 5925 MHz to 7125 MHz frequency bands supporting 5G n96, U-NII 5~8 and WiFi 7 & WiFi 6E applications. The DR filter composed of ceramic material offers high Q factors for excellent frequency selectivity, high attenuation, and temperature stability, ideal for 5G small base station, and WiFi 7/ 6E APs, routers applications.
The Dielectric Resonator filters feature compact package and low profile to be directly mounted on the main PCB of end-devices. Connection is made to the RF radio through microstrip transmission lines.
