Product Introduction:
1.HX3208 suite adopts electric tunning monolithic FM integration circuit,and tunning is convenient and accurate,has high sensitivity of receiving;small and light,easy to carry
2.Voltage 1.8-3.5V,internal structure has mute circuit to prevent from noise during tunning
3.Adopting low and middle frequency 70KHz technique,saving middle frequency and ceramic filter;the circuit is simple and reliable;modulation is coonvenient.
