Integration 2.0r manual Overview, Repeater Block Diagram

OVERVIEW

The demo’s main objective is to show the IA4420’s capability to monitor multiple frequencies, receive data from an FSK transmitter, and then re-transmit this data on an another arbitrary frequency to another receiver or transceiver. This demonstration is designed to show the IA4420 acting as a repeater node.

The Repeater Demo has three main components: the IA4420, which is the system radio, a C8051F311 type 8051 microcontroller, which controls the application, and a 2 line 16 character LCD, which informs the user of the repeater status

(Note).

The current version of the Repeater Demo is equipped with a 50 Ohm SMA connector for the antenna.
