Giga-tronics at the International Microwave Symposium highlighted its new 2500B series microwave signal generators, which cover the 100-kHz to 50-GHz frequency range with low phase noise and high rejection of harmonics, subharmonics, and spurious signals.
In addition to the flagship 50-GHz model, five other models are available, covering 2.5 GHz, 8 GHz, 20 GHz, 26.5 GHz, and 40 GHz.
The instruments incorporate Giga-tronics’ patented Accumulator High Frequency Feedback (AHFF) technology to delivers fast switching speed, typically less than 500 μs for a 1-GHz step and as fast as 100 μs for small steps. Sales and marketing VP Malcolm E. Levy says said that the instruments switch better than 10 times faster than their nearest low-noise competitors.
The close-to-carrier phase noise in the new series achieves specifications of -90 dBc/Hz at a 100-Hz offset and -102 dBc/Hz at a 1-kHz offset on a 10-GHz carrier frequency, making the 2500B suitable for radar and EW applications, where close to carrier effects on Doppler systems are becoming very relevant for slow moving targets, according to Levy. The generator noise performance at a 10-KHz offset is typically -110 dBc/Hz.
“The 2500B series is focused on the many applications in aerospace and defense, commercial
communications including satellite and microwave link, and microwave component test that require signal generators with agility and superior signal purity” said Levy in a press release. “We have already demonstrated to customers that with the high-speed performance of this generator we can significantly reduce their test times, an enormous benefit for improved productivity.”
The Giga-tronics 2500B output power is +13 dBm at 50 GHz in the standard model without a need for optional high power versions. For those applications that require much higher power, Giga-tronics offers a line of companion microwave power amplifiers offering a 1-db compression point of +40 dBm to 10 GHz, +35 dBm to 20 GHz, +23 dBm to 40 GHz, and +20 dBm to 50 GHz.
