433/868/915MHz FSK Two-way Wireless Transceiver Module with CMT2300 Chip


Module introduction

DL-RTM300&300H was designed base on CMOSTEK CMT2300A wireless transceiver chip, it is Pin to Pin with HopeRF's RFM300H/RFM300 RF modules. It is a compact, low-power, long-distance wireless transceiver module. It is mainly set to 433MHz, 868MHz, 915MHz and other special frequency bands of the national networks. The sensitivity can reach -120dbm, the maximum transmission rate can reach 300Kbps. The 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.
