cubesat uhf transceiver.There are three reasons why the receiver may be good or bad at work

　　In the working process of the infrared receiver, sometimes there will be a phenomenon of good or bad, far or near, in most cases, this is caused by the bottom sensitivity of the infrared receiver.

　　There are three common reasons for low sensitivity:

　　First, the standard pulse width of our infrared receiving head is generally 600us, if the infrared receiving head you use can not accurately synchronize when receiving signals, there is advance or lag, it will produce insensitivity.

　　Second, the interference of the surrounding environment, the interference of light, different light intensity, has an impact on its sensitivity.

　　Third, the impact of electromagnetic waves, requiring customers to produce their own products to eliminate or reduce the impact of electromagnetic wave interference

　　The infrared receiver is a sustainable high level output in the received signal, which is generally used in audio, toys and other products.
