BeRex Inc. has introduced multi-function front-end RFIC modules designed for 802.15.4 ZigBee, Bluetooth, THREAD and Matter applications.
The 8TR8218 and 8TR8219 combine a power amplifier for transmission with a low-noise amplifier for the receiver, a pair of SP3T (single-pole triple-throw) switches for transmit/receive/bypass functionality, along with a filter network and 50-ohm input and output matching circuitry. All of these are packaged in a compact 3.0 mm x 3.0 mm x 0.45 mm 16-pin QFN package.
The 8TR8218 and 8TR8219 offer cutting-edge technology, providing up to +23 dBm saturated output power and ultra-low noise figures of 1.6 dB to 1.9 dB. These devices can operate with a wide voltage range from 2.2 V to 4.0 V and an operating temperature range from -40°C to +125°C. Their enhanced energy efficiency makes them ideal for battery operation.
