Synthesizer applications abound with the more typical ones including wireless communications, precision clock sources, and radar and surveillance systems. To meet the evolving needs of such systems, the ultra-low-noise LN310 synthesizer covers the 1-to-310-MHz band with a +3 to +13 dBm output. It boasts 0.1-Hz resolution and a frequency switching speed below 5 s (to within 0.1 radian at new frequency). The device offers amplitude switching below 50 s (to within 0.25 dB at new frequency/amplitude). At a 100-MHz output, the synthesizer features less than 80 dBc discrete spurious with 152 dBc/Hz phase noise offset 100 kHz from the carrier. In contrast, a 310-MHz output translates into discrete spurious below 70 dBc and 142 dBc/Hz phase noise offset 100 kHz from the carrier. At 19 x 3.5 x 17.5 in. (relay rack or bench cabinet), it weighs 20 lbs. P&A: $3990; available with BCD or GPIB/USB/ LAN interfaces.
