Low Noise Prepolarized Microphone
378A04
The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

Full Band Phase Shifters
STP-18-10-M2
Full band phase shifters are micrometer-driven, waveguide-based phase shifters. The configuration of the micrometer-driven phase shifters is similar to that of level setting attenuators, where the phase shifting is caused by an E-plane dielectric insert in the rectangular waveguide. The amount of phase shifting is directly dependent on the volume of the insert. The VSWR and the insertion loss of these phase shifters are dependent on the frequency. The below standard offering covers the frequency range of 18 to 110 GHz and a phase shifting range of 180 degrees. These micrometer-driven phase shifters are typically used to introduce a certain amount of phase shifting when the absolute number is not a focus.
