Introduction

DL-RTM300&300H is a compact, low-power, long-range wireless transceiver module designed around a high-performance wireless transceiver chip. It operates primarily on dedicated national frequency bands including 433MHz, 868MHz, and 915MHz. The module achieves a sensitivity of -120dBm, a maximum data rate of 300Kbps, and a maximum output power of +20dBm. All RF-related functions are integrated within the module, enabling direct development of stable and highly reliable wireless products. With this RF module, no in-depth knowledge of RF circuit design is required, significantly shortening product development cycles.
