The 2500B series of microwave signal generators from Giga-tronics (San Ramon, CA) covers 100 kHz to 50 GHz with low phase noise, high rejection of harmonics, sub-harmonics, and spurious, high output power level. Six models cover 2.5, 8, 20, 26.5, 40, and 50 GHz. Accumulator High Frequency Feedback (AHFF™) technology delivers a switching speed of typically less than 500 μs for a 1 GHz step and as fast as 100 μs for small steps. Close to carrier phase noise is -90 dBc/Hz at 100 Hz. Generator noise performance is 10 kHz offset with a typical performance of -110 dBc/Hz. This series is suitable for radar and EW applications.

The generators feature an output power of 13 dBm at 50 GHz. For higher power applications, the company also offers companion microwave power amplifiers with 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.
