DL4900-200 is a state-of-the-art OFDM broadband radio transceiver for the 4800 - 5000 MHz Military and Homeland Security frequency band. The broadband radio transceiver can deliver IP based Video, Voice and Data services in Near Line of Sight (NrLOS) conditions. It features high data throughput with 1.3W Tx power, better Rx sensitivity and high SNR. DL4900-200 features Doodle Labs’ proprietary PrismTM technology with advanced filtering and noise reduction techniques for high interference immunity. The DL4900-200 is specially designed to deliver best performance in long-range outdoor applications and it has demonstrated the ability to provide high throughput even in extremely noisy environments.
DL4900-200 maintains distortion free signal at higher modulation rates to maintain low packet errors and maximizes data throughput. The design uses highly linear power amplifiers to deliver maximum power even at 64 QAM radio modulations while maintaining low distortion EVM (Error Vector Magnitude). With better Rx sensitivity and high SNR, DL4900-200 is specially designed to deliver best performance in long-range outdoor applications. The Industrial/Military grade design & enhanced resilience to RF surges & ESD makes it ideal for deploying in harsh environments.
