High Performance Superheterodyne RF Receiver Module with Infineon Chip
DL-RX98H is an ISM band high performance superheterodyne RF receiver module. This receiving module adopts industrial grade RF wireless data receiving chip from Infineon, which has high receiving sensitivity, and very strong anti-interference ability. It can realize wireless signal input to data signal output without any external circuit.
Its superior performance makes it a good choice as RF receiving module for the automotive RKE system. Users can easily develop wireless products by simply adding a data decoding circuit.
Features
● Operation frequency: 315 Mhz, 433.92 Mhz (customizable for special frequencies);
● The receiving sensitivity can reach -110dBm;
● Operation voltage: 5V;
● Low power consumption, 4.6mA; power consumption can be as low as 100nA in power enabled mode;
● Completely integrated VCO and PLL synthesizers;
● Good selectivity and stray radiation suppression, easy to pass safety test;
● Good local radiation suppression, can work together with multiple modules (one to many) and will not interfere with each other, the receiving distance also not been affected;
● Temperature range: -40~85 C (industrial grade), can work well even in harsh environment.
