A radio transceiver is a hardware device that combines a transmitter and receiver in a single unit to send and receive radio-frequency signals over a shared channel. It performs modulation, demodulation, amplification, and frequency conversion, forming the physical link layer of wireless devices. Transceivers underpin IoT nodes, mobile devices, and short-range wireless links.

- Transceivers handle modulation schemes (FSK, OFDM, LoRa), channel access, and power management, with low-power variants critical for battery-operated IoT endpoints. Integrated system-on-chip transceivers combine RF front-ends with microcontrollers and protocol stacks (BLE, Zigbee, Wi-Fi), reducing board complexity and cost.
