RF Transceiver

With extremely low-power requirements and highly integrated foundation, HOPE's RF Transceiver circuits and modules give you a low-cost and flexible solution for your RF Transceiver design. Our RF devices are versatile, multi-channel ISM band RF Transceiver IC and modules(optimized for design re-use), featuring programmable frequency, bandwidth, data rate and output power, etc. This makes our RF Transceivers well-suited for cost reducing legacy products and for next-generation RF designs.

The Low costing, high performance and price ratio RF Transceiver IC&Modules works with FSK modulated signal, Within the range of the 1GHz bands, tuning free during production, and comply with FCC, ETSI regulation. The SPI interface is used to communicate with microcontroller for parameter setting. It is widely used in such as remote control system, automated meter reading, home automation and access control, as well as high-quality speech, music and data transmission over RF.
