SYSTEM DESCRIPTION AND INSTALLATION MANUAL

JetWave™ System

• Contains an LNA for amplification of signals in the receive path.

• Includes the mechanical pointing system, positioner, motors and sensors, and an INU to detect

movement of the platform.

• The TMA or FMA accepts the transmit Ka-band signal from the KRFU for the antenna.

• The antenna K-band receive path is amplified by the LNA and sent to the KRFU by the TMA or

FMA.

• The TMA or FMA receives power from the KANDU.

• The TMA or FMA accepts the control interface from the KANDU and lets the antenna aperture

report status, BITE, and gyro position back to the KANDU.

• Radome packages are unique to each fuselage and can be made up of the kits that follow:

• Radome kit

• A791 compliant AIM or LAIM kit

• Skirt fairing.

NOTE:

Not all aircraft will have a skirt fairing.

B. KRFU

• Is made up of a BUC to convert the transmit IF frequencies (950-1950 MHz) to Ka-band

frequencies (29-30GHz)

• An HPA increases the signal strength for transmission by the antenna

• Contains a BDC to convert the received K-band frequencies (19.2-29.2 GHz) to IF (950-1950

MHz)

• Accepts 115 VAC aircraft power.

C. KANDU

• Receives commands from the Modman through an Ethernet interface to configure the

antenna/KRFU and reports status over this Ethernet interface.

• Contains the positioning algorithm to allow the pointing of the antenna with inputs from the IRU,

information from the RSSI detector in the Modman, and the IMU from the antenna.

• Provides power and control to the antenna.

• Provides control signals to the KRFU through the RS-422 interface.

• Accepts 115 VAC aircraft power.

D. Modman

• Is the overall controller of the system.

• Receives and transmits information to the KRFU along the IF frequency between 950-1950

MHz.
