RF Transceiver ICs

Integrated circuits that transmit and receive radio frequency signals. Commonly used in wireless communication systems including Wi-Fi, Bluetooth, cellular, IoT, and SDR applications.

• Key Features: Frequency range, modulation schemes, data rate, sensitivity, output power, low noise amplifier (LNA), phase-locked loop (PLL).
• Common Protocols: IEEE 802.11, BLE, Zigbee, LoRa, LTE, 5G NR.
• Package Types: QFN, WLCSP, TQFP.
• Supply Voltage: Typically 1.8V to 3.6V.
• Integration Level: Single-chip transceivers with on-chip VCO, PA, LNA, and baseband processing.

Popular Examples: nRF24L01 (Nordic), CC1101 (TI), ADF7021 (Analog Devices), SX1276 (Semtech), AD9361 (Analog Devices - SDR).
