Introduction receiver :
The ASK superheterodyne receiver module is a proprietary , patented technology uses low- voltage , micropower ASK superheterodyne receiver module . The module uses a high-performance RF integrated chip and high- Q dielectric resonator frequency stabilization , built-in temperature compensation circuit and ripple rejection circuit, with ultra-small size (12 * 18 * 2.1mm), low power consumption (1 .2mA), low- voltage wide supply voltage range (4.5-5.5V), high sensitivity, high stability, high anti-interference , high cost , etc. , can be lead-free certification , FCC, CE certification of the indicators are all kinds of remote control systems and wireless data transmission ideal system.

The module is widely used in remote control switch ; industrial control , communications and security fields, this receiver module suitable for complex environments , demanding circuit. No external circuitry that can do the wireless signal is input to the data signal output. Users need only simple data decoding circuit plus , you can easily develop wireless products.

The main receiver features 
1 , the industry's first high- Q dielectric resonator frequency stabilization technology to replace SAW resonators, frequency stability up to the level of positive and negative 150KHZ .
2, super anti- interference ability of the power supply , built-in ripple rejection circuit, switching power supply , power supply regulator and other strong ripple voltage divider circuit stability interference , eliminating three -terminal regulator IC to reduce costs.
3 , wide supply voltage range (4.5-5.5V) and extremely low power consumption, the unique power saving mode , the typical power consumption of 1.2mA, suitable for battery-powered devices.
4 , stable and reliable, has a wide operating temperature range.
5, with ultra-small size (12 * 18 * 2.1mm) ultra-thin thickness (2mm), on the back of the module without the device , you can close the circuit board installed.
6 , low self- radiation , through a variety of international testing standards.
