Vector Network Analyzers of Rohde&Schwarz family are able to measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. By means of the inverse Fourier transform the measurement results can be transformed to the time domain. Thus, the impulse or step response of the DUT...

Radar, satellite communications and 5G NR use AAS with phased array antennas for beamforming. Hybrid beamforming combines the flexibility of digital beamforming with the efficiency of analog beamforming.
Increasing integration enables compact and cost-efficient AAS. To achieve accurate, reliable and efficient beamforming,...

All electronic devices contain capacitive or inductive components that can cause a disproportionately high current while switching on the device.
From an FPGA to a drilling machine, virtually every component or device requires an inrush current that by far exceeds the normal operating current. To properly design the...

Vector Network Analysers (VNA) are gaining popularity in the Signal Integrity community as Time Domain Measurement and Analysis tools.
VNAs with 8 ports or more can provide significant decreases in test time by migrating from a 4-port measurement system to an 8-port measurement system. For tight tolerance DUTs...

In a design of a modern switch-mode power supplies (SMPS), the designer has to ensure that the converter is operating in its specified values over all circumstances. For example, some of these tests to ensure proper performance are output voltage deviation test, load transient test, output voltage ripple, input voltage...

One of the primary purposes of a gate driver is to enable power switches to turn on and off faster, improving rise and fall times. Faster switching enables higher efficiency and higher power density, reducing losses in the power stage associated with high slew rates. However, as slew rates increase, so do measurement and...

Deembedding, often a necessary and complex task, is made easier with an integrated hardware and software solution. Whether you are debugging a high-speed interface such as DDR or PCIe, characterising a fast clock or analysing a complex RF signal, you want to see the real signal and not artifacts of the test setup such...

This article examines how to synchronize multiple DC/DC buck regulators in a Master/Slave configuration using phase shift time delay. Phase shifting multiple converters prevents ON time overlapping and reduces RMS current, ripple and input capacitor requirements, which will improve system EMI and power efficiency. This...

There are four options for their DC/DC converters when determining the power needs for their end product. This paper will focus on the discussion of options (1) and (2) and it is intended to aid customers in deciding which of the two best meets their needs. Comparisons of performance, cost and time to market are made...

As a manufacturer of switches, quality is one of the most crucial elements of our brand. It is also one of the elements that we can control. If the switch doesn’t meet quality standards and tests that we expect from our manufacturing processes, it is discarded and destroyed.
This focus on quality is what all...
