Tunable Band Reject Filter RI 268
0.6-8 GHz, combined 5 & 160 MHz reject bandwidth, rack mount
Critical tool for adaptation to stringent ETSI/3GPP conformance test specifications for mobile device radio properties in device testing. Designed for formal conformance testing performed by accredited test houses, as well as internal verification by device vendors.
The Ranatec RI 268 is a digitally tunable band reject filter that covers a frequency range from 600 MHz to 8000 MHz, offering excellent performance for testing across multiple wireless communication standards. With selectable reject bandwidths and a high reject depth, it is ideal for precise conformance and interoperability testing in 5G, LTE, Wi-Fi, and Bluetooth applications.
