SECTION 2

20000DESCRIPTION

2.1. FMHPA SYSTEM GENERAL DESCRIPTION

The FMHPA forms part of the airborne SATCOM system, used in conjunction with a
Satellite Data Unit (SDU), a Diplexer/Low Noise Amplifier (DLNA) and a High Gain
Antenna (HGA) conforming to ARINC 781, with an internal Beam Steering Unit (BSU).

The TopFlight Satcom (TFS) system conforms to the Aeronautical Radio Incorporated
(ARINC) 781 Characteristic, and interfaces with onboard avionics and communication
equipment to provide the aircraft with a range of communication services by
transmitting and receiving L Band signals to and from the fourth generation of
INMARSAT satellites. For this purpose the INMARSAT satellite constellation is
connected to the ground backbone telecommunication network through Satellite Access
Stations (SAS) operated by service providers.

A. Hardware

The FMHPA contains two hardware Shop Replaceable Units (SRU):

• The Radio Frequency (RF) SRU which contains the High Power
Amplifier (HPA) and the RF Filter

• The Logic SRU which contains the Power Supply Module (PSM) and
the Communication Module (CM).

The two SRUs have a heat-skin with cooling fins and a nozzle to dissipate the
temperature.

(1) RF SRU

The RF SRU has two external connectors and two internal connectors:

a. External connectors:

• RF input (J2)

• RF output (J3).

b. Internal connectors, connecting the RF SRU to the Logic SRU:

• Power Supplies

• Communication signal.

(2) Logic SRU

The Logic SRU has one external connector and six internal connectors:

a. External connector:

The external connector (J1) is used to communicate with the SDU and for the power
supplies of the FMHPA.

b. Internal connectors are used to:

• Connect the PSM and the CM

• Connect the RF SRU to the Logic SRU for power supplies and the
communication signal.

• Supply a test connector for testing and downloading.

B. Software

There is no software in the FMHPA.

All FMHPA functions shall be allocated to hardware.

C. General Operation

The FMHPA is a Linear Power Amplifier for embedded communication system (TFS).
FMHPA supplies up to 35W RF power to the Aircraft Satcom antenna when the physical
separation of the SDU and the antenna is such that the RF loss between the SDU and the
antenna will be greater than that allowed in ARINC 781. Alternatively, the FMHPA may
be used in cases where more power is required than would be available from the HPA
within the SDU, to provide the services offered.

Its function is to amplify the modulated signals supplied by the SDU. The number of
signals to be amplified depends on the communication traffic, from a single up to the
maximum capability of the SDU. FMHPA also includes a constant and programmable
RF gain, a high grade of self test (90% of failures are detected) and a high temperature
protection function.

(1) Functional Modes:

The FMHPA operates in the following five modes:

a. Nominal Mode (35W output)

Nominal Mode (NM) is defined as the operating condition when power supplies are
applied. This mode is enabled by default at powerup, the power supply is defined at its
nominal Voltage (around +27V)

b. Low Power mode (9W output)

Low Power Mode is defined as the operating condition which can be enabled by SDU
(or FMHPA in security case) when the temperature is high and in order to reduce the
dissipated power (for example to save the internal temperature when there is a loss of
cooling). For this mode, the power supply is changed from Nominal Voltage (around
+27V) to Low Voltage (around +17V). Cockpit only services available.

With NM and LPM modes, the main characteristic of the modes is to maintain a constant
gain whatever the temperature.

c. Carriers Off/MUTE Mode

This mode switches off the RF gain, and puts the FMHPA in Standby (STBY) mode.

d. STBY / On mode

With Standby mode, the main characteristic of the mode is to have the lowest
consumption.

In this mode, the RF output power equals zero, and the thermal dissipation within the
FMHPA is reduced to the minimum possible to permit temperature monitoring and
