The 8775B4 is a male precision fixed termination with a 2.92mm connector, designed for use in high-frequency measurement systems to minimize signal reflection. It maintains a VSWR of 1.02 from DC to 4.0 GHz, 1.12 from 4.0 to 40.0 GHz, and supports a power rating of 0.5 watt CW and 0.25 kW peak. It is intended for applications requiring accurate impedance matching, such as VNA calibration.
A precision fixed termination (or load) consists of an immovable, (fixed) termination which, when mated to the end of a trans-mission line or cable, absorbs nearly all of the signal energy traveling toward it. An ideal “matched” condition exists when a termination with an impedance value of Z0, is connected to the end of a transmission line or cable that also has a characteristic impedance of Z0. Such an ideal “matched” condition (one with no mismatch between the termination and its mated line or cable) is critical if a voltage standing wave ratio (VSWR) of 1.0:1 is to be achieved in a system with a 50 or 75 ohm impedance value. Simply put, the more closely the 1.0:1 ratio is approached, the more accurate the measurements that can be made from a system.
