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. THALES AVIONICS Ltd.

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 © THALES AVIONICS Ltd.

This STBY mode can be obtained with four configurations: • Command configuration: In this case, an input command, Carriers Off/ Mute command from SDU, enable or disable the STBY mode • Auto-protection configuration: When FMHPA detect an internal failure (High level) and the SDU doesn’t answer within 2 seconds • With carriers Off/Mute, the main characteristic of the mode is to have a high isolation between FMHPA input and FMHPA output • After HPA Power-On Self Test (POST) or at the end of a self test. e. BITE Monitoring A monitoring Mode is defined in order to check if the FMHPA Status is OK or FAIL. A self test is carried out at Start-up and on request from the SDU. D. HPA Module The HPA function is to amplify modulated signals from the SDU, up to 35 W. The HPA includes an amplification chain, a digital part for control and communication and a RF filter. The output RF filter is a mechanical filter, without any electronic component, with a N connector output. E. PSM and CM Module The PSM and CM SRU module contains two modules in the same housing: • Power Supply Module • Communication Module. © THALES AVIONICS Ltd.
