Key Functional Highlights
-
Dual-Band Versatility: Unlike many entry-level chips, the WCN3660 supports both the crowded 2.4 GHz and the cleaner 5 GHz Wi-Fi bands. This is critical for avoiding interference in urban environments.
-
Integrated RF Front-End: The chip includes a built-in dual-band power amplifier (PA), low-noise amplifier (LNA), and transmit/receive switches. This reduces the need for external components, saving up to 50% of board space compared to discrete designs.
-
Intelligent Coexistence: It features a hardware-level coexistence engine. This prevents the Bluetooth signal from “drowning out” the Wi-Fi or LTE signals, ensuring that you can listen to music on Bluetooth headphones while downloading data over Wi-Fi without drops.
-
Advanced FM Radio: It doesn’t just receive FM; it can also act as an FM transmitter (FM Tx), allowing the device to broadcast audio to car stereos or older radios.
-
Low Power Architecture: Designed for mobile use, it features “Deep Sleep” and “Standby” modes that consume minimal current, significantly extending the standby battery life of the host smartphone.
Common Applications
The WCN3660 was widely used in iconic mobile devices from manufacturers like Xiaomi (notably the Mi 4), Sony, and LG. It is often a go-to replacement part for repair technicians dealing with “No Wi-Fi” or “Bluetooth greyed out” issues on older Snapdragon-based handsets.
