Sub-1GHz Micro-power Wireless RF Receiver Module 

DL-RXP4302 is a compact and micro-power Sub-1Ghz RF Modules based on the high-performance ASK wireless superheterodyne receiver chip. It has high stability, strong anti-interference and simple peripheral circuit. At the same time, it also has a strong driving force, which can directly drive the standard decoding chip or the decoding master chip.

This DL-RXP4302 RF receiving module strives to solve the problems of low power consumption and remote control in the process of product development, which uses the external crystal as the local oscillator, no longer uses the high cost acoustic meter resonator, and has good mass production consistency. It can be directly applied to your wireless products, or a variety of embedded applications, to avoid tedious high-frequency performance debugging and effectively shorten the development cycle.

The application frequency of this RF receiver module is typically 315MHz, 433.92mhz, but we also can customize the special frequency 390MHz for you. The normal receiving power consumption of this module is the lowest in the same kind of superheterodyne receiving scheme, and can pass the European/American radio safety test.


● 300m transmission distance in an open air (1200bps)

● Working frequency: 315M, 433.92M (390MHz can be customized)

● Ultra-wide operating voltage range: 2.4V-5.5V

● CE interface enables to control the sleep / wake-up state of the module

● The average power consumption of wake-up mode is less than 500uA

● Standby current of less than 0.1uA (in sleep state)

● Optional R25 discrete or PT4450 transmit system
