The RFM110/RFM117 devices are ultra low-cost, highly flexible, high performance, single-chip OOK transmitters for various 240 to 960 MHz wireless applications. The RFM110A covers the frequency range from 240 to 480 MHz while the RFM117 covers the 240 to 960 MHz frequency range. They are part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and ransceivers. With very low current consumption, the device modulates and transmits the data which is sent from the host MCU. An embedded EEPROM allows the frequency, output power and other features to be rogrammed into the chip using the CMOSTEK USB Programmer and RFPDK Alternatively,in stock products of 433.92/868.35 MHz are available for immediate demands without the need of EEPROM programming.The RFM110/RFM117 transmitter together with the RFM21x receiver enables an ultra low cost RF link.
