Feature

The KST-2000A/B incorporates a closed loop control system that

maintains the system's conversion gain (as measured from the IF input to

the Ku-Band SSPA output) at the user's preset value despite the effects

of temperature, aging, and cable loss. This feature is provided for use

with Comtech EF Data SSPAs up to and including 40W.

Optional on ordering.

Each KST-2000A/B converter unit contains the logic and switch drivers

necessary for redundant configurations when used with the RJU-2000.

There are several selectable serial communications:

•

An optional weatherproof keypad/display designed to control the KST-

2000A/B configuration parameters and to monitor the fault system.

An isolated output covers the 950 to 1700 MHz downlink bands.

The KST-2000A/B's internal reference may be locked to an external

standard at 5 or 10 MHz in order to reduce the system frequency errors

to that set by the external reference; or the high-stability, electrically and

mechanically tunable internal reference may be used.

A GREEN LED indicates prime power ON when blinking and TX RF

power ON when steady. A RED LED indicates a summary fault.

All KST-2000A/B power supplies have power factor corrected power

supplies and meet all CE Mark requirements.

The KST-2000A/B converter has built-in monitor and control circuitry and

functions that operate with the following equipment:

•

This flexibility enables adjusting the system's power output to meet

application requirements by simply changing the HPA.

•

The KST-2000A/B system components are completely weatherproof

units designed for the harsh environments of antenna-mounted systems.

The system's operating parameters can be monitored and controlled

using Windows™ based M&C software with a personal computer, a

keypad/display built into the KST-2000A/B, or a hand held KP-10 as

described in Chapter 3.
