Introduction
The Eclipse2 series is a Software Defined Radio (SDR) Base Station designed for Conventional
Analogue FM and Conventional APCO P25 modes of operation.
Utilising a DSP and RISC platform
The base station uses a modular design concept, which provides extensive flexibility for users, e.g.
stand alone transmitter/receiver, cross-band repeater operation, etc. Utilizing DSP technology and
the built-in Ethernet port, all operating parameters can be monitored and controlled remotely.
A typical base station or repeater system includes a Reciter (Receiver & Exciter); an RF power
amplifier; and a switch mode or linear power supply. All the modules can be plugged into a RF
Technology standard 19 inch 4U high rackframe.
The Reciter can deliver up to 5 Watts RF output power, the power amplifier in some configurations
may not be required, this allows more than one Reciter (up to 6) to be mounted into a single 19
inch rack.
