This is a low-power 3GPP 5G/4G/3G transceiver IP optimized for cellular applications. It integrates all the necessary RF/analog/mixed-signal functions for a 3GPP Universal/5G/4G/3G 2x2 transceiver for low cost and low-power applications with fully integrated frequency synthesizer. It offers a high level of programmability, making it an ideal universal radio.
The receive path (RX) has very high dynamic range and is implemented with direct-conversion architecture. A direct conversion TX generates low EVM signals to drive the external power amplifier. Two fully integrated Frac-N frequency synthesizers and LO-chains generate the required low phase-noise LO signals for TX and RX mixers. A complete GPS receiver with a frequency synthesizer is also integrated.
It offers unique Intellectual Property (IP) portfolio for various wireless markets, including Wi-Fi, 5G/4G/3G, Bluetooth, Zigbee, and GNSS among others. The ultra-low-power transceiver IPs enable Internet-of-Things (IoT) and Machine-to-Machine (M2M) applications.
