Agilent / HP 8349B

The Agilent / HP 8349B Microwave Amplifier delivers increased microwave power performance across a 2 to 20 GHz frequency range.

The Agilent 8349B is a general- purpose broadband power amplifier which is designed for maximum reliability and configured for the greatest convenience in interfacing with Agilent's microwave sources, the Agilent 8350B Sweep Oscillator, Agilent 8340B/8341B/8360 Series Synthesized Sweepers, and Agilent 8671B, 8672A, or 8673 series Synthesized Signal Generators.

Providing 100 mW (+20 dBm) of unleveled output power from 2 to 18.6 GHz, 63 mW (+18 dBm) from 18.6 to 20 GHz, the Agilent 8349B offers one of the broadest operating bandwidths available from a solidstate power amplifier.

This performance is achieved using a multiple stage GaAs FET design, resulting in > 15 dB of gain from 2 to 18.6 GHz, and > 12 dB of gain from 18.6 to 20 GHz.

The Agilent / HP 8349B can also provide externally-leveled output power without using an external coupler and detector, since these components are built-in and are compatible with Hewlett-Packard microwave sources.

The Agilent / HP 8349B is also equipped with an output power display, minimizing the need for an external power meter and enhancing the amplifier's utility.

For example, the Agilent 8349B can be placed at the end of a long RF cable where the microwave output needs to be amplified, leveled and monitored. Naturally, the versatile power control features of the microwave source (e.g., calibrated power, power sweep, power slope and remote power control via the Hewlett-Packard Interface Bus) can be accurately transmitted through the Agilent 8349B during external leveling operations.

The Agilent 8349B also has a built-in source module interface, enabling it to properly bias and control the Agilent 83550 series millimeterwave source modules.

Using the Agilent / HP 8349B and a millimeter source module extends the capabilities of any 11 to 20 GHz HP microwave source to millimeter-wave frequencies.

The broadband high power of the HP 8349B is ideal, whether in a versatile bench-top arrangement or a dedicated rack-mount system. In antenna testing, the HP 8349B can be placed at the end of long RF cables, delivering high power right to the device under test.

In EW/ECM systems, the HP 8349B can be combined with the HP 8340B/8341B/8360 Series, or the HP 8673 series Synthesized Signal Generators to provide high power pulses with little degradation in pulse performance.

The HP 8349B is also an excellent choice as a microwave driver for TWTs, high power amplifiers, or mixers. And with a typical noise figure < 13 dB, the HP 8349B is often used as a pre-amplifier for spectrum analyzers and frequency counters.
