Model No.: DL-R11A

Description: super hyteredyne wireless receiver module/RF receiver circuit board 433Mhz

Product Detail:

DL-R11A is a kind of UHF high frequency receiving module with perfect stable performance, adopting advanced high integrated receiving IC RX3400 that has interior VCO and PLL circuit. It is widely applied in some circumstance with high interference and severe conditions.

1. Application:

a. Wireless gate security system;

b. Various anti-theft system;

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

d. Data transmit with low band rate;

e. Other wireless remote control.

2. Technical Specifications:

3. Size and Pin definition

4. 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.
