Description
●STA3005 is a high-performance, fully programmable advanced radio receiver, designed to target AM/FM/HD radio, speech and audio applications. It is a dual-IF radio processor, with dynamically variable channel filtering; it also features both digital diversity (for dual-tuner systems) and digital directional antenna (single-tuner multiple antennas) for outstanding reception capability.
