Model FE-798A
Model FE-799A
A militarized, high reliability RF distribution system
for satelllite ground stations and shipboard, mobile, and laboratory
applications.
Features
 Low
phase jitter signal distribution with spurious signals 120 db below
the carrier.
As many
as 56 outputs with 95 db of isolation in a single chassis.
Modular
construction allowing module replacement without disturbing system
operation.
Redundant
signal distribution with automatic switchover to standby modules.

The primary Distribution Unit, Model FE-798A, and
Secondary Distribution Unit, Model FE-799A, have been designed for
the low-noise distribution of reference signals where reliability
is of paramount importance. Systems are available for distribution
of frequencies from 1KHz to 100 MHz. Low noise synthesizer modules
generate any desired output frequency from the reference input.
With solid-state modular construction, these systems offer outstanding
performance and versatility, along with ease of maintenance.
The system is redundant and expandable and consists
of rack mountable carriers with plug-in modules that enable the
rapid implementation of a wide variety of system configurations.
Outstanding performance capabilities include...
• Low phase jitter signal distribution with
spurious signals 120 db below the carrier.
• As many as 56 outputs with 95 db of isolation in a single
chassis.
• Modular construction allowing module replacement without
disturbing system operation.
• Redundant signal distribution with automatic switchover to
standby modules.
• Self testing capability with module fault indicators and
summary alarm outputs.
• Qualification tested to meet rigorous military requirements
for temperature, humidity, shock, and vibration.
• EMC design to meet MIL-STD-461 and MIL-STD-462.
The primary and Secondary Units can be interconnected
to provide an all-purpose distribution system or the units can be
operated individually to meet less complex mission requirements.
The module carriers used in the Primary and Secondary Distribution
Units have been carefully designed to insure the interference free
distribution of rf signals for any combination of modules that may
be utilized.
Each module is of machined construction to provide
electrical performance which is totally insensitive to environmental
variations. Low noise, wideband circuit designs in conjunction with
advanced component encapsulation techniques ensures that vibration
induced phase modulations are virtually non-existent. Ê
