Technical Overview: 5989-5743EN
www.keysight.com/find/mta
Low-noise and system amplifiers for signal conditioning
Ultra-broadband, high-performance amplifiers eliminate the need for crossover networks and multiple power supplies to support multiple narrowband amplifiers.
Product Terms
Noise figure: An excellent amplifier noise figure significantly reduces the overall test-system noise figure.
Gain: High gain increases available power to spectrum analyzers and improves test-system sensitivity.
Key Features
-
Broadband performance up to 50 GHz optimizes the operating range of your test systems
-
High-output power boosts available power for measurements
| Key Product Differentiator: Excellent noise figure and gain significantly reduces overall test system noise figure across broadband frequency up to 50 GHz. |
