Model No.: DL-R11C

Description:Adjustable bandwidth low voltage RF receiver module

   

Product Detail:

DL-R11C adopts the latest high integration UHF receiving IC from Synoxo of France, it can work under UHF frequency of 300~440Mhz. Compare with traditional receiver module, it is with less components, wide working voltage range, adjustable bandwidth, more stable performance etc. It is widely applied in some circumstance with high interference and severe conditions.

Notes for usage

a. Pls use soft lead wire or other hard metal (like telescopic antenna), It can not be either too long or too short, or it will affect the receiving distance. The antenna should be stretched as straight as possible if it is using soft lead wire, and as far as possible from the metal objects.

b. The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)

c. We suggest the clock frequency of the MCU should be lower than 4MHZ if used together with MCU, the crystal should be as far as possible to the RF receiving module, or the higher harmonic of the crystal will affect the communication distance.

d. There is short distance signal block up problem during the work of the ASK receiver module, pls pay attention to it during the operation.
