Function Introduction

This wireless high-frequency receiver module RWS-434N is through

WENSHING R&D team assembled many years of experience to develop this

high sensitivity OOK receive module. Lost cost, high stable also can providethe best RF solution in the market.

Design ideal is to use SAW filter, highly suitable for industry control or bad

place for use, strong anti-jamming.Built-in automatic gain circuit (AGC), it will

automatically change front-end LNA gain among received signal strength also

makes signal output will not be strong or weak signals which caused by phase

distortion, so that it can rise higher sensitivity. To receive the local oscillation

circuit for the PLL lock loop design, no offset, and stability is high.

Frequency is 433.9MHz and receiver structure is super heterodyne, received

signal is OOK. After received signal, it will output TTL signal to external

decoder IC for decoding.

It is convenience to use in different products and external components is not

necessary to make products be wireless also bring value-added for your

products.
