What is 5G NR filter ?

5G NR (New Radio) system has been recently published by 3GPP in December 2017. It follows LTE technology called as 4G. There are two frequency bands supported by 5G NR devices viz. FR1 and FR2. FR1 is from 450 to 6000 MHz where as FR2 is from 24250 to 52600 MHz. The filters designed for use in 5G NR devices are known ad 5G NR filters.

The filters used should support less than 6 GHz and greater than 6 GHz bands. Various methods have been followed since years in RF filter designs. Following table summarizes common filter technologies.

Filter type Frequency range
SAW filter Up to 2.5 GHz
BAW filter Up to 6 GHz
FBAR filter Up to 10 GHz
Dielectric Waveguide Up to ~ 30 GHz
Waveguide Up to ~ 80 GHz
On chip Up to ~ 70 GHz
Microstrip Up to ~ 70 GHz

As mentioned in the table, SAW filters address the requirement of RF filters up to 2.5 GHz and BAW filters up to 6 GHz. The other filter types address mmwave (millimeter wave) band requirements of 5G NR devices. FBAR type address requirements of 5G filter up to 10 GHz. Waveguide filter and cavity filter are used for frequency range from 20GHz to 80 GHz.

Following are the parameters or criteria is used in selection of appropriate 5G filter for your 5G NR development.
• Percent Bandwidth
• Selectivity
• Insertion Loss
• Size and Packaging
• Temperature stability
• Power Handling
• Filter Placement

5G NR systems need RF filters with high percent bandwidths, excellent temperature stability, low insertion loss, transmit power as per range requirement, good selectivity and so on.
