RF Transceiver Module RFM69HCW 433MHZ

RF Transceiver Module RFM69HCW 433MHZ

RF RFM22B ISM Transceiver Module 868MHZ

          HopeRF's RFM22B/23B are highly integrated, low cost,433/868/915MHZwireless ISM transceivers module. The low receive sensitivity(–121dBm)coupled with industry-leading +20dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend the range and enhance performance. Additional system features such as an automatic wake-up timer, low battery detector, 64 bytes TX/RX FIFOs, automatic packet handling, and preamble detection reduce overall current consumption and allow the use of lower-cost system MCUs. An integrated temperature sensor, general-purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost and size. The RFM22B/23B’s digital receive architecture features a high-performance ADC and DSP based modem which performs demodulation, filtering, and packet handling for increased flexibility and performance. The direct digital transmits modulation and automatic PA power ramping ensure precise transmit modulation and reduced spectral spreading ensuring compliance with global regulations including FCC, ETSI. An easy-to-use calculator is provided to quickly configure the radio settings, simplifying customer's system design and reducing time to market.
