GENERAL TECHNICAL DESCRIPTION

A universal power supply provides operation world-wide. An LED on the front panel verifies the presence of power

to the internal circuit board.

Selective filtering ahead of the low noise, high intercept RF amplifiers reduces intermodulation problems caused by

overload in the RF amplifiers. The filters provide a factory settable bandwidth of 16 to 50MHz.

Note: The frequency range and bandwidth is set at the factory and can be found by the serial number on the rear

of the unit.

Each antenna input feeds a ceramic filter assembly. The antenna outputs are coupled to the filter assemblies via

“strip lines” (1/4 wave transmission lines) built onto the circuit board, which function as RF power dividers.

Each ceramic filter module feeds eight outputs on the rear panel.
