BX-RM12 -433 is based on a single-conversion, super-heterodyne receiver architecture and incorporates an entire Phase-Locked Loop(PLL)for precise local oscillator generation. It can be used in OOK\/HCS\/PWM modulation signal and demodulate it to digital signal. BX-RM12 -433 have a high performance at a competitive cost and easily to design your products. \u003c\/span\u003e \u003c\/span\u003e\u003c\/div\u003e\n\n\u003cdiv style=\"font-family: Arial, Helvetica, sans-serif;\"\u003e\u003cspan style=\"line-height: 18px;
