8449A Agilent Preamplifier


The 8449A is a 22 GHz Preamplifier from Agilent. An amplifier is a type of electronic test equipment that amplifies radiofrequency (RF) and microwave signals using the antenna. Amplifiers are ideal when used for electromagnetic interference (EMI) testing, cell phones, microwaves, radio communications, and other such applications.

  • Detection and Analysis of Extremely Low-Level Signals

The Agilent HP 8449 Preamplifiers are low-noise, high-gain amplifiers that are connected between a signal source and the RF input of any spectrum analyzer. The combination of high gain and low noise figure enables the 8449A to enhance analyzer performance by greatly reducing the overall system noise figure. This improved sensitivity allows detection and analysis of extremely low-level signals. The frequency range of the 8449A is 2.0 to 22.0 GHz.

The 8449A is housed in compact, industry-standard, half-width System II packages that can be easily rack-mounted in traditional automatic test equipment (ATE) systems.
