The transceiver maintains distortion free signal at higher modulation rates and high power to maintain low packet errors and maximize data throughput. The design uses highly linear power amplifier to deliver maximum power even at 64 QAM radio modulations while maintaining low distortion EVM (Error Vector Magnitude). The transceiver employs fine tuned Low Noise Amplifier on the the receive chain to obtain better Rx sensitivity and high SNR. The transceivers are specially designed to deliver best performance in long-range applications. The Industrial/Military grade design & high resilience to RF surges & ESD makes it ideal for deploying in harsh environments.
