RFM22B FSK Module Cost High Performance ISM Band RF Transceiver Module RFM22

Description
- RFM22B is a low-cost, high-performance ISM band RF transceiver module. RFM22B highly integrated, reducing BOM cost and simplifies product design, appropriate to shorten the development cycle. High sensitivity (-121dBm) and high power output (20dBm) feature extends the communication distance and significantly improves the quality of communication. diversity and support for frequency hopping function within the integrated antenna makes the performance can be further improved. Meanwhile, Maple also provides a simple and convenient calculator for quick configuration parameters in order to register simplify system design and reduce customers' products to market cycles.
