868/915MHz FSK Transmitter

Evaluation Board Description

General Description

The TH72031 evaluation board is designed to demonstrate the optimal performance of the transmitter IC in a

50Ohm environment with the minimum of external components. The TH72031

board is populated for FSK transmission. The power amplifier is optimally matched to 50 Ohm by means of

an antenna matching network for the resonant frequency of 868 MHz or 915 MHz.

Board layout data in Gerber format is available on request.
