www.bhe-mw.eu 2 DEAR READERS, PARTNERS, This overview is not a product catalogue. The main aim of this brochure is to provide a short summary about our products, services and capabilities. During the last 25 years, we developed more than five hundred different products, starting from the simple oscillators up to complex, space borne phased array communication terminals or different microwave subsystems of deep-space ground stations. These results are supported by more than 600 years of accumulated engineering experience we have. The products you will find in this brochure are just some reference samples to indicate our various capabilities in SATCOM technology. If you need something else, something what is not included please contact us for further information.

www.bhe-mw.eu 3 INTRODUCTION BHE Bonn Hungary Electronics Ltd. is a 100% privately owned company, based in Budapest, - Hungary. RF and Microwave R&D and manufacturing are our main focus. We are present already a quarter century in different communication markets, including mobile, critical, defense and aerospace, - where we have both onboard and ground segment solutions. BHE currently employs a hundred highly skilled specialists, some of them holding academic degrees. Our company is export oriented, - around 70% of our revenue comes from foreign customers. BHE is a founding member of HATP (Hungarian Aerospace Technology Platform), - a professional organization with member institutions and companies having real space heritage. MAIN REFERENCES In the last years BHE developed some special products for Satellite Ground Support and Space borne Applications. Our S-, and Ku-band tracking down converters (below) are widely used on ISRO ground and ship-based tracking stations for communication with India s First Mars Orbiting Satellite ( Mangalyaan ). BHE developed different RF and microwave devices for ESA DSN Stations and converters for DLR Tracking Stations. Our satellite video receivers are used by LAPAN (Indonesian Space Agency) in their daily work with the Indonesian LAPAN TUBSAT satellites. The German DLR and the Korean KARI use BHE s satellite control transmitters on their ground stations. Among the ground segment solutions we have developed some products for onboard applications. For example, one of the major US satellite service providers uses BHE s SDR based redundant digital on-board modulator in their AIS constellation. Our high quality S-Band, 40 W Solid State Power Amplifier is in operation on the International Space Station Zvezda module.
4 www.bhe-mw.eu SYNTHESIZERS AND OSCILLATORS BHE developed a significant number of different frequency synthesizers for airborne or SATCOM applications up to Ka-band. These programmable local oscillators provide clean output signal, low phase noise, compact, easy handling and high resistance against shock and vibration. THE PHASE NOISE OF BSVX21 BSVX20 BSVX21 SYNTHESIZERS Our innovative BSFL12 is an L-band fast switching synthesizer and multiple signal source. Its main features are 1 tuneable and 4 fix frequencies, fast switching time, very low harmonics and excellent phase noise. The L Band high speed tuneable signal covers 100 MHz wide range with 1 MHz steps. The operational frequency range stretches from 1520 up to 1620 MHz and the step frequency is 1 MHz. The fix output frequencies are 30, 40, 240 and 400 MHz respectively. The ruggedized BSFL12 operates between -40 C and +70 C, and it is qualified by the MIL-STD-461E and MIL-STD-810D EMI/EMC standards. BSFL12
5 www.bhe-mw.eu MODULATORS, TRANSMITTERS In BHE s modulator portfolio, customers will find basic FM and PM modulators such as: BUMT15 and BUMT16. In addition to the basic modulation tasks, these two modulators up-convert the IF signal to C and S band respectively. Excellent RF parameters, high linearity and low distortion characterise the units. BUMT15 C AND BUMT16 S BAND SATELLITE MODULATOR AND UP-CONVERTER BUMT15 BUMT16 For local control purposes the units has pushbuttons and LCD display. All relevant parameters can be set and checked in a clear and user-friendly menu. The external connection can be realised through TCP/IP port. Informative graphical user interface provides access to key functions and settings. CONTROL SOFTWARE SCREENSHOT
6 www.bhe-mw.eu FREQUENCY CONVERTERS Existing models cover the generally used satellite communication bands e.g. L, S, C, X, Ku and Ka. The conceptual block diagram of the up-converter is shown in the Figure below. CONCEPTUAL BLOCK DIAGRAM OF UP-CONVERTER Block or tuneable converters indoor, or hub-mountable construction units are available to fully meet the system requirements and architectures. In order to increase the availability and reliability BHE supplies 1:1 or 2:1 redundant converter systems. All units can operate as stand-alone or in automatic hot redundancy configuration. 1:1 (LEFT) AND 2:1 (RIGHT) REDUNDANT SYSTEMS
www.bhe-mw.eu 7 FREQUENCY CONVERTERS The Centre Unit (CU) represents the heart of the system. The CU is responsible for monitoring the whole system via internal data bus. The vital information of the status of the converters is collected and sent to the user. In case of any failure, the system changes automatically to the reserve unit. In addition, there is a manual changeover capability. The modular construction makes BHE s products flexible and custom tailored. All components are selected carefully in order to achieve the highest level of reliability and availability on a 24/7 basis. 19 rackmount construction, outdoor up-converters, LNB-s, LNA-s (see next page) are also important part of our SATCOM portfolio.

www.bhe-mw.eu 10 SOLID STATE POWER AMPLIFIERS BHE s power amplifiers contain four sub-blocks - see below the conceptual block diagram. The preamplifier section generally incorporates two to three amplifier stages and a digitally controlled attenuator to adjust the overall gain of the amplifier. This section provides the major part of the gain and appropriate signal level to drive the high power final stage. TYPICAL TRANSMISSION CURVE, THE GAIN VARIATION IS LESS THAN 1 DB SUMMARY WINDOW OF CONTROL SOFTWARE The high power final stage consists of one or more power FET. When high output power is necessary, more power FETs are used. Higher output power is achieved by combining the power of more amplifier stages. The bias voltages and currents are monitored at component level. Each sub-module has a built-in temperature sensor. In order to increase the availability and reliability, BHE supplies 1:1 or 2:1 redundant power amplifier systems. All units can operate both in stand-alone and fully automatic hot redundant configuration.
