Model No.: DL-R23AF

Description: 1Mhz bandwidth anti-jamming RF receiver module   

 

Product Detail:

DL-R23AF super heterodyne receiver module which adopts DL-R18A anti-jamming receiver circuit, the receiving bandwidth is very narrow, the ability to anti-interfere of mixed wave is high. It has the feature of stable performance. It can be used independently as it has included 2272 decode circuit. It can be widely used on all kinds of occasions with high interfere and idious situation.

 

Application:

a. Remote receiving system of garage door with high motor interfere;

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

c. Various regular anti-theft receiving system;

d. Data transmitting system with wireless low boud rate.

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. Please pay attention to the conformity of rate and code format between encoding IC and decoding IC, otherwise the inconformity will affect communication distance or even break off the communication.
