The Keysight (Agilent) 11975A is a general-purpose, leveled microwave amplifier covering 2 to 8 GHz with an output adjustable from +6 to +16 dBm. Designed for high-performance applications, it features automatic level control (ALC) with on/off switching and an “unleveled” indicator light. It includes an adjustable bias current output (up to 11 mA at +3 V) for powering external harmonic mixers, making it an optimal LO driver for the Keysight (Agilent) 11970/71 series mixers.
This compact amplifier is engineered for precise signal boosting in microwave systems, ensuring stable output and easy integration with RF setups.
