1 General Description
In this configuration a sturdy and splash proof antenna pedestal houses the following sub-assemblies:
• Built-in, X band, solid state controlled Transceiver;
• Transceiver DC Power Supply and external AC/DC converter box;
• Antenna motor & reducer;
• High performance plastic gear wheel
• RF rotary joint;
• Proximity switch for antenna data transmission (azimuth and heading line) or encoder with 1024
pulses.
• The antenna is an End Fed Slotted Waveguide type.
• Selectable antenna rotation speed.
The above compact arrangement allows a direct coupling between Transceiver and rotary joint, thus simpli-
fying the installation work and significantly reducing the RF losses normally accepted when the Transceiver
is installed into a separate cabinet in “down-mast” position. The interface with the radar console is trough a
single connector and it is not necessary to open the transceiver casting during installation. Every analog
adjustment is made remotely from the Selux console.
The pedestal with built-in 12kW or 25 kW transceiver supports 6´/ 9´/ 12´ antennas.
Both Transceiver and motor driver are fed by a 48 VDC supply, an external transformer is required for
115/220 VAC 50/60 Hz power supply.
The Transceiver has new compact electronics with a high integration level derived from a well-tested de-
sign.
Main features:
• Modular and solid state construction;
• Electronic Modulator based on MOSFET technology;
• Long life 3

generation magnetron (10/12 KW and 25 KW);
• Low Noise Amplifier providing a reduced overall Noise Figure (4.0 dB nominal);
• Microcomputer controlled operations;
• Serial link with telemetry and remote control for adjustments;
• Built-in test facilities for power supply and modulator parameters;
• PRF jittering removing any possible ambiguity due to multiple-time-around echoes;
• Two different Sectors Blanking to be set at time of installation;
