　　描述

　　Dolphin is a Frequency Hopping Spread Spectrum (FHSS) Wireless UART chipset for the 902-928 MHz US ISM Band. The Dolphin chipset consists of the TRF6903 RF transciever and the digital baseband ASIC DBB03A and comes FCC pre-certified.

　　DOLPHIN-HP-EVM is the evaluation kit for the High Power Dolphin chipset. With this hardware the user is able to demonstrate, test, and evaluate two way point-to-point communication. The evaluation kit contains:

　　Two High Power daughter cards

　　Two Interface cards

　　Two RS-232 Serial Cables to connect to a computer

　　Graphical evaluation software

　　All applicable literature and data sheet

　　To demonstrate the broADCast capability of the Dolphin chipset, an additional adder kit is available. Please see DOLPHIN-LP-ADDER for a low power adder kit, or DOLPHIN-HP-ADDER for a high power adder kit.
