-105dBm sensitivity super regeneration RF receiver module

RF receiver module 1. super regeneration 2. -105dBm sensitivity 3. Factory price 4. OOK/ASK

Model No.: DL-R01B

Description: -105dBm sensitivity super regeneration RF receiver module

Product Detail:

DL-R01B super regeneration receiving module is adopting imported SMD components, 6.5G high-frequency triode and high Q value inductance, which make this module have the features of stable performance, high sensitivity, low power consumption, high quality and competitive price. This module is widely applied in anti-theft system and remote control system.

 

Application:

a. Receiving of various digital signal at low rate;

b. Industrial remote control, remote measurement and remote sensing;

c. Anti-theft alarm signal receiving and various remote controls for home-appliances.

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.
