Sub-4 GHz 5G-4G 2x2 RF IP

OverviewFeaturesRequest Datasheet

It is a low-power sub-4GHz 5G/4G transceiver IP optimized for 5G/4G applications. It integrates all the necessary RF/analog/mixed-signal functions for a 3GPP Universal/5G/4G/3G 2x2 UE/eNB 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.
