22GHz Wideband Microwave Generator


SKU: SG22000L Category:


[2023 Q1 Lead Update: In stock and ready to ship!]

Upgraded hardware revision and firmware for Feb 2023 with lower phase noise, less harmonics, and smaller frequency step size!

The incredibly compact SG22000L (replaces SG6000LDQ) Microwave Signal Generator delivers the widest frequency coverage on the market for its size and low price. The two output bands cover the ENTIRE range of 60 to 22000+ MHz. Output power is calibrated between -20 and +10dBm in 0.5dB steps up to 12.5GHz. The 12.5-22GHz band outputs a typical +15dBm signal for driving high power mixers or other Ku-band equipment. The crisp OLED display provides useful feedback for the user, and front control buttons provide a quick alternative to USB control. The output waveform is fully synthesized using modern fractional-N synthesis. This synthesized signal source can automatically detect and accept an external 10 MHz reference OR it can use its own ±280PPB internal 10MHz TCXO reference. Like most of our products, the SG22000L easily fits in the palm of your hand, making it a truly portable and bench-space-saving device. Ethernet now comes standard (2023).

Looking for lower phase noise and adjustable calibrated power output? Try the SG22000PRO!

We can also build this model without OLED display or buttons for integration inside another system.
