Elcom’s UFS family of microwave synthesizers meets today’s most demanding testing needs found in the laboratory, on production lines, and in system development and maintenance. The UFS delivers an unsurpassed combination of ultra fast switching speed, extremely low phase noise, low spurious, and wide frequency tuning range with small frequency step size. The basic advanced direct analog frequency synthesizer architecture provides for ultra fast switching speeds. This is complemented by a high speed direct digital synthesizer (DDS) subsystem implemented within the fastest available COTS FPGA. The DDS subsystem provides for small frequency step size with low spurious. Proprietary fixed frequency, low-phase noise PLL technology for the internal fixed frequency sources, along with the lowest phase noise VHF OCXO commercially available, yields extremely low phase noise.
Application of the latest semiconductor technologies for microwave and digital circuitry reduces parts count and reduces power dissipation, leading to high system MTBF. The standard configuration for the UFS is a rack-mount instrument, however, its modular internal layout facilitates configuration of the system to meet a limitless range of special custom synthesizer requirements for packaging and performance.
The architecture of the UFS has been developed to provide various high-level as well as basic optional functions. These include:
The IBS wideband low phase noise microwave frequency synthesizer covers the full 50 MHz to 20 GHz tuning range with a tuning step size of 10 Hz and with tuning speed of less than 200 microseconds. Based on Elcom's proprietary PLL indirect frequency synthesizer technology which utilizes high speed digital signal processing, the IBS is a cost-effective solution for a wide range of demanding frequency synthesizer applications. An AM modulator, a fast pulse modulator, and multiple 60 dB range variable attenuators are integrated within the IBS system. While the IBS is often used as stand-alone laboratory instrument, with its exceptional RF performance, signal control features, and options for interface and packaging, the fast tuning IBS is ideal in the ATE environment and in OEM systems.
Application of the latest semiconductor technologies for microwave and digital circuitry within the IBS reduces parts count and reduces power dissipation, leading to high system MTBF. The IBS is offered in two standard packaging and interface configurations: 19 inch rack-mount with GPIB interface, and 3 slot VME format.
The front panel is designed to allow all major functions to be operated easily and without extensive operator training. The operator is guided through various settings and operations via a multi-line LCD and keypad for data entry. All operating modes and features can be invoked from both the front panel and remote control interface. The unit can also be provided without the front panel interface and controlled exclusively via the remote control interface. The functions of the IBS/VMESG Series instruments are divided into groups on the front panel that make changing settings easier.
The IBS/VMESG Series is a family of synthesized signal sources based on indirect PLL technology with an internal direct digital synthesizer for fine resolution. Elcom's VCO/PLL design approach realizes much faster switching speeds, superior microphonic performance, lower phase noise, and lower power consumption than traditional designs.The instruments have trigger inputs, an Ethernet control interface with programmable frequency list mode, and can be supplied with or without a front panel that has controls for local operation. They are also available in a VME configuration.
These instruments are excellent choices for use in automated test systems to provide the primary test stimulus, or to provide a local oscillator (LO) signal. Other applications include radar and electronic warfare systems in which broadband coverage, low phase noise, fast switching speeds, and high reliability is of primary importance. Any IBS/VMESG model can be provided with an internal pulse modulator that modulates the RF output signal according to an externally supplied digital pulse input signal.
Each IBS/VMESG Series synthesized signal source passes rigorous inspections and tests prior to shipment. Every VMESG synthesized source is shipped in operational condition and no special installation procedures are required other than providing AC power.
No special cooling is required when operating the IBS Series instruments. However, for best results it should be operated in a temperature-controlled environment. Ambient temperature variations during use will affect the repeatability and accuracy of measurements made using the instrument. The synthesized source remote unit has a fan to dissipate heat.
The single-loop RS Series PLL Synthesizers employ Elcom’s proprietary design architecture to provide low phase noise and fast switching speed, <50 microseconds, in a compact ruggedized configuration. These synthesizers maintain specified performance under conditions of vibration up to and exceeding 6 G RMS. Operating base plate temperature range is 55°C to +85°C.
The RS Series PLL Synthesizers are ideal for the LO in spread-spectrum military airborne and ground based communications systems. They have application in many types of radar and ECM systems and in other types of communications systems.
The RS-1093 is a compact, rugged modular frequency synthesizer covering 105 MHz to 205 MHz with 5 KHz step size and it delivers +14 dBm output power, adequate for directly driving the mixer port on a frequency converter. The unit is controlled remotely through a parallel digital interface allowing for fast 100 microsecond tuning speed. The architecture of the synthesizer is based on an analog PLL configuration enhanced with a DDS and digital processor operating with an external 100 MHz reference. This design delivers exceptionally low spurious and phase noise.

Miniature, Low Cost Synthesizer Series
The LNMFS family of modular sub-octave coverage frequency synthesizers achieves exceptionally low phase noise in a rugged, compact package. Within the LNMFS, basic PLL indirect synthesizer architecture is enhanced using DDS and FPGA technology. This allows small step size and low spurious output levels to be achieved with moderate switching speed. The serial interface simplifies designing the synthesizer for any system application.
This family of efficient, low phase noise compact modular frequency synthesizers achieves small frequency step size through a fractional-N synthesis configuration designed for low phase noise and low-spurious outputs. A microcontroller handles digital IO and communicates with and optimizes the fractional-N PLL for the current set frequency. GaAs and SiGe MMIC devices provide for efficient RF and microwave signal processing. The low overall power consumption realized with this architecture results in reduced operating temperature and higher reliability, and it allows use of a smaller DC power supply. These synthesizers provide substantial performance margin for the phase noise requirements of IESS-308, Eutelsat, and MIL-STD-188 for fixed and mobile SATCOM ground stations. The MFS frequency synthesizer product family has over five-thousand units in field operation and is proven for high reliability under a wide range of operational conditions.
