SYN470R 300MHz-440MHz ASK Receiver

The SYN470R is a single chip ASK/OOK (ON-OFF Keyed) RF receiver IC. This device is a true “antenna-in to data-out” monolithic device. All RF and IF tuning are accomplished automatically within the IC which eliminates manual tuning and reduces production costs. The result is a highly reliable yet low cost solution. 

All IF filtering and post-detection (demodulator) data filtering is provided within the SYN470R, so no external filters are necessary. One of four demodulator filter bandwidths may be selected externally by the user. 

The SYN470R offer two modes of operation; fixed-mode (FIX) and sweep-mode (SWP). In fixed mode the SYN470R functions as a conventional super-heterodyne receiver. In sweep mode the SYN470R sweeps a wider RF spectrum. Fixed-mode provides better selectivity and sensitivity performance and sweep mode enables the SYN470R to be used with low cost, imprecise transmitters.
