Cellular network section schematic for the Samsung SM-A22 5G, a 5.26 MB PDF. It covers the RF chain, including transceiver, power amplifiers, antenna switches and the supply rails for the radio, relevant to both LTE and 5G bands. Use it for no service, dropped signal or emergency calls only faults, checking PA voltages, antenna feeds and RF lines. Because the 4G A22 is a separate design, confirm the board is the 5G variant and match component markings before replacing RF parts.
