Model No.: DL-R03C Description: RF receiver module for lighting Product Detail:DL-R03C is a very widely used super regeneration receiving module. It is new developed to be more perfect based on DL-R03A & DL-R03B, The high frequency receiving module has the features of stable performance, high sensitivity, low power consumption, high quality and competitive price. This module is widely applied in anti-theft alarm system of car, motorcycle, electrical vehicle, home application, lighting and MP3 etc. This module is very easily to pass FCC and CE. 1. 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.2. Technical Specifications:Operating voltage: 5.0V±0.5V Operating current: ≤4.5mA (5.0VDC) Operating principle: super regeneration Modulate mode: OOK/ASK Frequency range: 250MHz-450MHz Bandwidth: 2MHz (315MHz, test when the sensitivity decline to 3dBm) Sensitivity: better than -102dBm (50Ω) Rate: <5Kbps (at 315MHz at -95dBm) Output signal: TTL electric level signal entire transmission Antenna length: 24cm (315MHz), 18cm (433.92MHz) 3. Size and Pin definition4. Notes for usagea.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.
