5G NR ARFCN to Frequency Conversion Calculator

This document describes a 5G NR ARFCN calculator that performs conversions between NR ARFCN and frequency for 5G New Radio (NR) systems. It also explains the formulas used for these conversions.

5G NR, like LTE, adheres to 3GPP specifications, specifically the 38-series (while LTE uses the 36-series). In 5G NR, RF reference frequencies are identified by an NR Absolute Radio Frequency Channel Number (NR-ARFCN) on the global frequency raster.

The relationship between the NR-ARFCN and the RF reference frequency (F_REF) in MHz is defined by the equation below, where F_REF-Offs and N_Ref-Offs are found in table 5.4.2.1-1, and N_REF represents the NR-ARFCN.

5G NR ARFCN to Frequency Conversion

The following calculator converts a 5G NR-ARFCN to its corresponding 5G frequency:

Example:

• Input: 5G NR ARFCN = 444000
• Output: 5G RF Center Frequency = 2220 MHz

Formula:

The following formula is used to calculate the 5G NR frequency from the 5G NR ARFCN:

5G NR Frequency to NR ARFCN Conversion

The following calculator converts a 5G NR frequency to its corresponding NR-ARFCN:

Example:
