Band-Reject Filters are Digitally Tunable from 600 to 6,000 MHz

Oct. 10, 2024

A family of next-generation filters from Ranatec empowers electronics manufacturers in enhanced testing.

Ranatec introduced the digitally tunable RI 282 bandpass filter, digitally tunable between 600 to 6,000 MHz. Important tools to address the latest stringent ETSI/3GPP conformance test specifications for mobile-device radio properties, the tunable band-reject filter covers all sub-6-GHz mobile bands and channel bandwidths for 2G/3G/4G/5G, as well as Wi-Fi 4/5/6/6E/7, Bluetooth, and all sub-8-GHz channel plans.

Useful for design verification, product certification, and product testing, the tunable band-reject filters are designed for formal conformance testing, as well as internal verification by mobile-device vendors.

Filter characteristics remain constant across the entire frequency range, and frequency extension units are available as an option to extend the passband up to 26.5 GHz or 40 GHz. The RI 282 active filters conform to all existing sub-6-GHz mobile bands, and can be selected with high-end requirements that will remain unaffected over the tuning range.

Features include a combined 20- and 100-MHz bandwidth, a frequency tunable between 600 to 6,000 MHz, characteristics selected in runtime, and remote control via LAN. Additional features of the rack-mountable device include 75-MHz filter slopes and 50-dB suppression, with adjustable gain.
