30GHz Variable-Gain Amplifier


SKU: GB30000 Category:


Our latest high-frequency smart amplifier – updated for 2023!

The wideband GB30000 provides a compact and affordable way to amplify signals from 20-30GHz for a variety of Ka and K-band applications. Simple USB-C power input and control makes this device much faster to integrate, and more flexible than traditional multi-voltage lab-supply powered devices. All negative voltage generation, gate control biasing, current limiting, temperature monitoring, and voltage detection are done internally automatically.
