The adjustable compensation network at the input allows test engineers to tune the signal transmission lines within their fixed-connectivity test systems just as an engineer using a probe to manually test circuits would while also lowering capacitive loading compared to standard BNC and SMA cables.
With high speed transmissions, a PTH produces excessive capacitive loading, mainly due to the large pads at the PTH ends, which lead to impedance mismatch and signal discontinuity.
The various techniques used in the past for the miniaturization of Wilkinson Power Divider involve 3D techniques [1], Planar artificial transmission lines [2], Capacitive loading [3], stepped impedances [4], large inductance through the application of transverse slits [5], substitution of quarter wave section with lumped parameters [6,7], varacter tuning [8], open stub technology [9], periodically loaded stubs [10] etc.
High capacitive loading can slow down signal edges while inductance from the probe ground-lead combined with capacitance from the probe input can form a series-resonant circuit that can appear as ringing.
Including the capacitive loading from the fringe fields to the anti-pads, the differential via impedance is approximately
Although ICs are available that provide both ESD protection and level shifting for the HDMI high-speed video/audio signal lines, as well as the two control channels, this removes the flexibility for designers to choose the best video/audio-protection IC offering the highest bandwidth and lowest capacitive loading.
X2Y typically uses less capacitance than normally required for filtering, resulting in less capacitive loading to the data line.
In order to minimize skew, it is imperative that line lengths and capacitive loading be matched within the signal pairs and then compared to skew between other pairs to minimize the signal pair to pair skew.
The SP4040-02BTG Series provides market-leading lightning protection with a minimal capacitive loading of only 2.
This increases capacitive loading and lowers bandwidth both because of the matrix capacitance and the cabling capacitance," he explained.
Engineers have concerns about capacitive loading, so probe manufacturers provide a capacitance specification.
12] The spur line sections are [lambda]/4 in the passband, and require capacitive loading at the ends in order for the transmission zeroes to occur in the image band.
