2.4G High Power RF Transceiver Module for Aeromodelling Use
Module introduction
DL-297LPA is a single-chip wireless transceiver module which works in ISM band of 2.400 ~ 2.483ghz. The module integrates RF transceiver, frequency generator, crystal oscillator, modem and otherfunctional modules, which supports “one to many” networking and communication mode of ACK.Transmission output power, working channel and communication data rate can be configured.
This module is a low cost 2.4G RF module with low power consumption, 2μ sleep current, and very few components, it has a compact size but excellent performance, easy to use. Its transmitting power is up to 20dbm, with strong anti-interference performance, high near channel rejection of the receiving filter,and good receiver selectivity.
The module adopts single chip architecture, high-precision crystal, high Q-value Murata inductor and small volume high-capacity filter capacitor. SMD components are used in the whole system, and the interface adopts stamp edge packaging form with standard spacing, which is conducive to the development of compact system and the application of SMD mass production.
