This is the 3rd Generation SDR RF IP that supports 1x1 and a frequency ranging from 100MHz to 2.6 GHz, which is currently in TSMC 40nm. The SDR Gen.3 supports the ADC/DAC with 80Msps sampling speed. The SDR RF IP also supports TDD/HD-FDD and is optimized for IoT applications
This SDR RF IP family are ultra-low-power radio solutions optimized from IoT and M2M to 5G applications. They integrate all the necessary RF/analog/mixed-signal functions to support radio functions for most standards operating in this frequency range at low-cost and ultra-low-power.
The receive path (RX) has very high dynamic range and is implemented with direct-conversion architecture without external SAW filter. A direct conversion TX generates low EVM signals to drive the external power amplifier. An integrated Frac-N frequency synthesizers and LO-chains generate the required low phase-noise LO signals for TX and RX mixers. Optional fully integrated power management can be integrated to minimize the module eBOM cost.
This unique SDR RF IP family support many wireless market standards, including: 5G, Wi-Fi, LTE, NB-IoT, 802.15.4g, 802.11ah, Bluetooth, LORA, GNSS/GPS among others. This ultra-low-power transceiver IP enables Internet-of-Things (IoT) and Machine-to-Machine (M2M) applications.
