\"\"<\/a><\/p>\n

DL435-30<\/strong> is a state-of-the-art, high performance embedded OFDM radio transceiver specially optimized for the frequency band 420 MHz ~ 450 MHz (70 cm). It features high data throughput with up to 600 mW Tx power, better Rx sensitivity and high noise immunity. DL435-30 features Doodle Labs\u2019 proprietary PrismTM hybrid heterodyne technology with advanced filtering and noise reduction techniques for high interference immunity and long range applications. The DL435-30 has demonstrated the ability to provide high throughput even in extremely noisy environments. The rugged construction of DL435-30 makes it ideal for deploying in carrier class equipment.<\/p>\n

DL435-30 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 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, DL435-30 is specially designed to deliver best performance in long-range applications. The Industrial\/Military grade design & enhanced resilience to RF surges & ESD makes it ideal for deploying in harsh environments.<\/p>\n
