2 fs5000 series fast switching synthesizer the frequency generation technique used by the fs5000 is direct analog frequency synthesis, implemented in a patented, iterative, modular, architecture. based on mixing, adding and dividing fixed frequencies using wide-band mixers, ultra-fast switches and switched filter banks, this technique is singular in providing, simultaneously, the attributes of fast switching speed, high spectral purity and wide frequency range. direct analog frequency synthesis is also inherent - ly rugged and reliable - there are no loops to unlock and no vibration sensitive oscillators. the fs5000s fundamental frequency generation range is 4.8 to 13.5 ghz, an order of magnitude higher than the fs2000. synthesis at x band microwave frequencies allows for wide bandwidths, small size, and superior spectral purity. the output frequency can be extended to 26.5 ghz using one doubler, which increases spurious signals and phase noise by only 6 db. fs5000 technology consequently provides not only superb frequency agility, but also spectral purity rivaling low noise fixed frequency references. at x-band the fs5000 delivers 200 ns frequency switching time, phase noise of -120 dbc at 10 khz offset, spurious signals better than -70 dbc, and harmonics suppressed to better than -50 dbc. modular fs5000 synthesizers with special - ized low noise references are available with improved phase noise of -130 dbc at 10 khz offset and spurious signals better than -80 dbc at x band. the programming and digital interface for the fs5000 are fully compatible with aeroflexs fs2000 family of synthesizers. aeroflex develops and manufactures the specialized components used in implementation of the fs5000 architecture. thick film hybrid microcircuits, fabricated in the companys boca raton, florida facility, contribute to the unmatched performance and reliability found in the fs5000. wide-band switched filter banks and ultra-fast switches are manufactured by aeroflex tailored to fs5000 specifications. standard kits to support frequently used frequency ranges are available in compact packages. the instrument realization is housed in a 3u rack mountable chas - sis with display, keyboard, ieee-488 interface, and parallel bcd interface for fast switching control. these are designated b series and plug into standard power mains, both u.s. and international. the b series is supported by a number of standard options which tailor the unit to specific system or laboratory requirements. oem versions are typically supplied with modules mounted on plates and require external regulated power - exact configuration is application dependent. typical examples are given in this data sheet. oem versions can be supplied to meet a broad spectrum of performance and physical requirements ranging from commer - cial to full military airborne. actual phase noise plot at 9 ghz of modular radar upgrade system 8.0 ghz output spectrum showing 2nd harmonic at 16 ghz, no sub-harmonic at 4.0 ghz and spurious signals better than -80 dbc actual oscilloscope photo showing 6.5 to 13.5 ghz step in 103 nanoseconds signal & control sol utions aerofex signal & control solutions www.aerofex.com/ascs ? acc-sales@aerofex.com revision date: 8/21/2013
3 fs5000 series fast switching synthesizer fs5000 technology has been developed to support the most stringent airborne requirements. the architecture as well as its implementation has been specifically geared to furnish - ing military qualified, high reliability units. the architecture developed around direct analog frequency synthesis is inher - ently insensitive to vibration - there are no vcos or sensitive phase locked loops. the components and modules supporting the architecture have also been selected for their rugged and temperature stable qualities. all elements of the architecture have components which can be qualified to mil-std-883. the architecture has been implemented using the most appropriate technology presently available. in order to support the need for miniaturization and low power drain, much of the implementation is carried out as application specific hybrid microcircuits. these are designed and produced by the aeroflex circuit technology div - ision, supported by a 25,0000 square foot, milstd- 1772 qualified, microelectronics production facility. fs5000 technology permits a truly modular approach to the design of specialized frequency synthesizers. the architecture itself is interative and modular, herefore implementations are naturally so. specific frequency ranges and step sizes are produced by using standard and semi-custom modules configured to support the precise requirement. this architectural approach is adapt - able to a wide range of applications, and also accrues all of the advantages of standardization. reliability, service, logistics, and development economy are all substantially enhanced by using fs5000 architecture and technology. the fs5000 is the signal source of choice for implementing advanced radar systems but also for upgrading existing radars. the above paragraph shows an upgrade to an agile fire control radar. the upgrade consists of a down converter, an instantaneous frequency measurement (ifm) module, a control processor, and an fs5000 agile syn - thesizer. the principle of the upgrade subsystem is to measure the agile radar pulse frequency at transmission and accurately set the receiver local oscillator (lo) before the return pulse has arrived. the lo must be accurate with respect to frequency, have low phase noise and low spurious content - attributes for which the fs5000 is ideally suited. aeroflex/comstron produced the complete upgrade subsystem including real-time control and self-calibration capabilities. the fs5000 p1 oem plate illustrated shows a typical modular configuration. electrical connections for power and programming as well as rf output are located to promote interface accessibility. the placement of standard modules allows for proper channelling of airflow for cooling. the location of module input and output connections are in easily accessable locations. this feature aids in service and trouble shooting. future expansion or enhancement of this basic synthesizer is possible with the capability to add or replace modules or upgrade existing modules. additional information on standard modular sets of oem plate (p) series configurations is provided below. signal & control sol utions aerofex signal & control solutions www.aerofex.com/ascs ? ascs-sales@aerofex.com revision date: 8/21/2013
