Lekha WaveGuru Nava – Hardware platform is an ideal platform for 5G Small cell, 5G CPE, 5G Fronthaul and several other communication and EW applications demanding wide band data transceiver and processing.
Lekha WaveGuru Nava – 5G Hardware platform board is a Xilinx RFSoC based SDR board capable of hosting multiple Waveforms. The on-board wideband and RF sampling ADC and DAC ensures that with minimal change in the RF front end circuit, several combinations of Transmit power, receive gain, Multiplexing schemes (TDD/ FDD), can be achieved.
The Platform solution comes in a combination of the RFSoC board and a Radio Front end (RFE) board. The two boards are connected through the LPAF Interconnect. The RFE board has the needed Balun circuits and the Gain stages to deliver 23dBm power per DAC port. The receive chain has a 18dB LNA stage.
The RFE board is available for 3.5GHz TDD operation.
