Fast Switching Synthesizer

The FastSource™ frequency synthesizer family represents a

milestoneinthedevelopmentofhighspeed,lownoisesignalsources.

Designed specifically to meet the needs of today’s fast-paced

telecommunications test industry, this product offers a high-

performance, cost effective solution for the increasingly complex

demands of the ATE market.

DrawingonAeroflex’sexpertiseinbothdirectandindirectsynthesiz-

er design, the FastSource™ combines the best features of both. The

classic compromise between direct and indirect synthesizer

designs is essentially a tradeoff between speed and spectral

purity.

Direct analog synthesizer design utilizes wideband, open loop cir-

cuitstomaximizefrequencyswitchingspeed,usuallyattheexpense

of noise floor performance. Indirect synthesizer design, based on

phase-locked loops, optimizes noise performance by using rela-

tively narrow PLL bandwidths. The resulting response times are

on the order of several tens to hundreds of microseconds.

Direct analog designs are hardware-intensive, requiring numer-

ous RF and microwave filters to suppress spurious responses. In

applications where sub-microsecondswitching speedisnot essen-

tial, these designs tend to be cost-prohibitive. Indirect designs offer

better noise floor and spurious performance than the typical

direct design, but the slower response time can be the limiting

factor for throughput of an ATE system. Indirect designs never-

theless offer a major cost advantage over direct.

With the FastSource™ design, Aeroflex has successfully combined

high speed and low noise performance in a single, cost effective

product. This unique combination offers ATE system designers a

solution to demands for greater throughput with more stringent

test requirements.
