Agilent / HP 8348A
Microwave Amplifier
Description
The Agilent/HP 8348A is a general purpose broadband instrumentation amplifier capable of providing gain and power to overcome systematic RF losses, drive high power devices, improve measurement system performance, and drive millimeter-wave source modules.
Systematic power losses include switching and signal routing in ATE systems, frequency conversion, and long transmission paths to remote devices like antennas. These losses can be overcome by using the 8348A.
The 8348A provide power to drive and characterize high power devices like mixers, power amplifiers, TWT’s and optical modulators which are very level-sensitive.
Filter rejection and switch isolation are examples of device characterizations requiring a great deal of dynamic range. The 8348A can be used to increase low level sweep speed in increased dynamic range measurements using a network analyzer.
Key Points
Up to 25dBm output power
Reduced systematic Power losses
