315-433MHz ASK Ultra Low Power Superheterodyne RF Receiver Module KL-CW05 

Micropower Superheterodyne Receiver Module



1. Characteristic

  •  Using industry’s first stabilization frequency technology with a resonated cavity of high quality factor instead of SAW resonator. The frequency stability is up to ±150kHz of SAW. No crystal and adjusting elements.
  •  Using high performance RF IC.
  •  Built in automatic temperature compensation circuit.
  •  Ultra high anti power interference. Built in ripple rejection circuit, can work stably in high ripple interference environment such as switching power source, voltage regulator tube potential divider power supply, etc, so that no need the triode voltage regulator IC, reduce your cost.
  •  Wide power supply range (2.7-3.3V), very low power consumption. Special power saving working mode, typical current is 0.28mA, particularly suitable for the device which is powered by batteries.
  •  Ultra small size (12mm×18mm×2mm). No components on the back of board, can be pasted to the PCB tightly.
  •  Ultra low emission, can easy pass all kinds of certification.
  •  Stable and reliable, wide range working temperature.
  •  Support short antenna, receiving well with 4-5cm long antenna
  •  High sensitivity.
  •  High performance-price ratio.
  •  Lead-free, very environmental.

8. Last but not the least

In tandem with society's progress, now people around the world look forward to more convenient life. So RF remote control system has broader and broader prospect.  Compare to IR remote control, RF has more advantages. It is easily to match receiver, and can be used freely. It can cross the wall and other obstacles. And the operation distance can reach from few meters to thousands meters depends on transmitter power and receiver sensitivity.

Our RF remote control system is widely used in home automation system, home and business alarm security system, industrial automation control system, auto door / gate / window / curtain system, LED light control system, and so on. 

Remote control system frees the users, so that they have more time to do other important things and enjoy their convenient life. Whatever you want to do, just need to press a button, then you can make it easily. Whatever the world changes, you definitely need remote controls. Remote control is the world, we are the world.

Shenzhen Kelvin Electronics Co., Ltd. is a professional manufacturer in RF field in China. We always provide high quality products with competitive price. Most of our products have passed the CE, FCC, RoHS and other certification. 

We also do OEM and ODM professionally. Our remote control system has already been used in solar panel auto control system in AustraliaLED light auto control system in Canada, water pump auto control system in Mid East, home early warning system in Italy, etc. 

We have developed 99-channel remote control which can control max 99 devices with one remote control. And we also have developed FSK remote control which can reach more than 1km. Our remote control duplicators can copy other remote controls and replace them, it uses our own programme. KL180-4K and KL240-4K are the top selling remote control duplicators. We sell over 10,000pcs per month to EU, Southeast Asia and Latin America. 

Our product items are limited, but our dream is unlimited. To enter your life, free your hand, and make you more convenient, reduce your cost, that is our dream.
