Aeroflex Announces 2200 Series Fast Switching Frequency Synthesizers
Now Guaranteed for 12,000 Hours Continuous Operation

The performance leader in frequency synthesis for over 20 years, the 2200 family is ideal
for high-speed applications such as radar, antenna testing and EW simulation

FORT WORTH, Texas — International Microwave Symposium — June 8, 2004 — Aeroflex Incorporated (Nasdaq: ARXX) today announced it has made major design enhancements to its line of fast switching frequency synthesizers and is announcing its 2200 series; improving continuous operation—the Mean Time Between Failure (MTBF) by three times—from 4,000 hours MTBF to 12,000 hours MTBF. The 2200 family is built on a versatile modular platform that is the fastest and cleanest available today. It offers one microsecond switching speed and sub-microsecond level correction, coupled with superb spectral purity.

Designed to save substantial time and money over building a custom system in-house, the 2200 family is used for airborne, shipborne, electronic warfare simulation, radar upgrades and other stringent applications where the highest performance is required for rugged environments. The 2200 family is ideal for radar simulation, radar cross-section measurements, antenna pattern measurements and other high-speed microwave and RF applications.

2200 family spans frequency range from 10 MHz to 18.4 GHz

The 2200 frequency synthesizers are broadband sources, operating over the range of 10 MHz to 18.4 GHz with a standard resolution of 1.0Hz. The 2200 family can step from any frequency (F1), to any other frequency (F2), up or down, in 1 uSec. Output amplitude is +10dBm +2 dB into an impedance of 50 Ohms. The 2200 family includes over 30 models and is housed in a full 3U rack chassis with front panel keyboard for manual control, GPIB, and parallel binary coded decimal (BCD) interface for remote programming. Aeroflex’s modular architecture and iterative frequency models make it ideally suited for custom OEM applications. Just two standard modules make up a 10 MHz – 2.3 GHz, 100 MHz resolution OEM synthesizer with the same specifications as the standard family, needing only DC power and frequency reference. To obtain finer resolution and/or wider frequency coverage, the user can easily add other standard modules.

Aeroflex frequency synthesis enables low noise, spectral purity

The frequency generation technique used by the 2200 family is Direct Analog Frequency Synthesis modular architecture. Based on mixing, adding and dividing fixed frequencies using wideband mixers, ultra-fast switches and switched filter banks, this technique is unique in providing, simultaneously, the attributes of fast switching speed, high spectral purity and wide frequency range. Direct Analog Frequency Synthesis is also inherently rugged and reliable—there are no loops to unlock and no vibration-sensitive oscillators.
The 2200’s architecture with a central reference generator synthesizes 50, 100, 150, 200 and 800 MHz signals from a 100 MHz reference derived by multiplying a 5 or 10 MHz reference oscillator appropriately and improving far-out noise by judicious filtering. All frequencies are derived in an iterative frequency generation architecture. Frequencies are generated as a decade of frequency steps over an octave from 500 MHz inputs to the next stage. Final outputs are produced by a scaling module that provides for doubling, dividing or heterodyning to achieve a range of 10 MHz to 2.3 GHz.


The 2200 family is available immediately upon receipt of order. The 2200 family is modular with over 30 configurations possible and more with options.
