FSK Wireless Transceiver Module with Silicon Labs si4463 Chip
Product Description
High-performance FSK Transceiver Module with Si4436 chip
Module introduction
DL-RTS4463PA was designed base on Silicon Labs' Si4463 wireless transceiver chip. It is a compact,low-power, long-distance RF transceiver module with power amplifier. The chip launched by Silicon Labs is mainly set to 315MHz, 433MHz, 868MHz, 915MHz frequency bands of the national networks. The sensitivity can reach -124dbm, the maximum transmission rate can reach 1000Kbps, and the output power is amplified by high frequency power transistor to +27dbm @ 6V PA voltage.
This RF transceiver module integrates all RF-related functions. Users do not need to have a deep understanding of RF circuit design; they can use this module to easily develop wireless products with stable performance and high reliability, shortening the product development cycle.
The module uses a single-chip architecture, with high-precision crystals, high Q-value Murada inductance and small volume of high-capacity filter capacitor on the periphery. The power device uses Japanese imported power tubes and harmonic matching. The interface uses standard spacing stamp edge packaging to facilitate remote applications. DL-RTS4463 wireless module can be used together.
