What is a RF Receiver Module? View: 906319 Author:Jame Publish Time: 2020-05-20
An RF receiver module receives the modulated RF signal, and demodulates it. There are two types of RF receiver modules: superheterodyne receivers and superregenerative receivers.
Superregenerative modules are usually low cost and low power designs using a series of amplifiers to extract modulated data from a carrier wave. Superregenerative modules are generally imprecise as their frequency of operation varies considerably with temperature and power supply voltage.
Superheterodyne receivers have a performance advantage over superregenerative; they offer increased accuracy and stability over a large voltage and temperature range. This stability comes from a fixed crystal design which in the past tended to mean a comparatively more expensive product. However, advances in receiver chip design now mean that currently there is little price difference between superheterodyne and superregenerative receiver modules.
DL-RTS1278 transceiver module feature the LoRa long range modem that provides ultra‐long range spread spectrum communication and high interference immunity.
DL-RX98H is an ISM band high performance superheterodyne RF receiver module with RF receiving chip from Infineon, which has high receiving sensitivity, and very strong anti-interference ability
DL-RXR4126 is an ISM band high quality superheterodyne ASK wireless receiving module. This module uses low noise large-scale integrated circuit, has a very high cost-performance ratio, perfect anti-static protection, and high reliability.
DL-RXB3 series RF module is a universal wireless receiving module for ASK and FSK modulation, which adopts imported industrial grade radio frequency wireless data receiving chip.
