Ranatec, a part of the Qamcom group and supplier of specialized test and measurement equipment for RF and microwave applications, announced it has added a new, state-of-the-art band stop filter for RF test and measurement to its product portfolio. First of its kind on the market, the Ranatec RI 268 tunable band reject filter covers all sub-6 GHz mobile bands, channel bandwidths and all sub-7.125 GHz Wi-Fi channels. The benchmark new RI 268 provides comprehensive coverage of all sub-8 GHz channel plans for design verification, product certification and product testing.

“Harnessing Ranatec’s proven expertise and continued focus on the design and manufacturing of premium quality test and measurement equipment for the most demanding niche RF and microwave applications, the Ranatec RI 268 Tunable Band Reject Filter 600 to 8000 MHz targets device testing for mobile 2G/3G/4G/5G as well as Wi-Fi 4/5/6/6E/7 and Bluetooth,” confirmed Magnus Kilian, CEO at Ranatec.

The RI 268 has been developed for formal conformance testing performed by accredited test houses and internal verification by device vendors.

• Ranatec’s newest instrument is designed to aid test houses and mobile device vendors in meeting the extensive set of ETSI/3GPP and Wi-Fi Alliance conformance test specifications (TS 136 521-1 for LTE, TS 138 521-1 for 5G NR and IEEE 802.11 for Wi-Fi) stipulating levels of radio properties to be verified for enabling high quality wireless access of mobile devices.
• Two key objectives for the conformance test specification are to detail requirements applicable for any mobile device with respect to transmitter output spurious emissions and receiver blocking characteristics.

The Ranatec RI 268 state-of-the-art, programmable band reject filter extends the dynamic range in spurious emission measurements by at least 30 dB by selectively suppressing the desired transmitted signal, leaving spurious outputs unaffected. To enable adequate verification of receiver blocking characteristics, the RI 268 is easily   configured to lower the noise level at selected receive frequency from any signal generator up to the same amount.

Product features:

• Targets formal conformance testing by accredited test houses and internal verification processes executed by mobile device vendors
• Critical tool for adaptation to stringent new ETSI/3GPP conformance test specifications for mobile device radio properties covers all sub-6 GHz mobile bands and channel bandwidths for 2G/3G/4G/5G
• Supports spurious emissions and blocking tests for Wi-Fi and Bluetooth bands up to 7.125 GHz.
• Future proof for applications up to 8 GHz.
