Agilent Technologies Inc. introduced a series of broadband microwave test accessories specifically optimised for communications and aerospace/defence applications. The innovations embedded in this series provide broadband capability and enhanced measurement accuracy, which expand the test and measurement capabilities in the communications and aerospace/defence industries.

Agilent's series of microwave test accessories is comprised of a 67GHz DC block, a 67GHz fixed attenuator, a 50GHz power limiter, and 50GHz absorptive PIN diode SPDT and SP4T solid state switches. The N9398G DC Block provides RF performance up to 67GHz with greater than 15dB return loss, 1dB insertion loss and temperature stability. This increases measurement accuracy while suppressing DC signals that can damage test instrumentation.

The Agilent 8490G precision fixed attenuator exhibits attenuation accuracy and a low standing-wave-ratio of 1.45GHz up to 67GHz. It comes with six attenuation options: 3-, 6-, 10-, 20-, 30- and 40dB.

The Agilent N9355F power limiter provides broadband input protection from excess RF power, DC transients, electrostatic discharge and accidental power overloads for a variety of RF and microwave instruments and components. It has an integrated DC block at both input and output ports to block signals below 10MHz and pass signals up to 50GHz.

Agilent's 50GHz spdt and SP4T solid state switches are characterised by high port-to-port isolation (above 90dB) and a switching speed of less than 1 microsecond. These switches are suitable for applications in communication, radar, and antenna test systems that require high-speed microwave switching up to 50GHz. Additionally, the absorptive characteristic of these switches provides impedance matching, which increases measurement accuracy.
