return loss

Return loss This is the ratio of the reflected wave to the input signal and is expressed in dB, and is also called return loss. The sign is negative and the larger the absolute value, the higher the performance (less reflection). The key to improving performance is stabilizing the characteristic impedance […]

Are "Floating structure" and "high-speed transmission" contradictory requirements?

Can "Floating structure" and "high-speed transmission" be compatible? In October 2020, at the same time as CEATEC, we announced the "10143 series" as a "Board to Board Connectors that 'combines' Floating structure and high-speed transmission." (20 […]

Regarding definition of supported data rate of FPC / FFC Connectors

Regarding the definition of the data rate supported by FPC / FFC Connectors In the measurement using the reference FFC (length 100/200/300mm), define the following two points Definition 1: Determined from the S parameter at differential 100Ω, The lowest value (recommended […]

VSWR/voltage standing wave ratio

VSWR/Voltage Standing Wave Ratio Voltage standing wave ratio, a parameter that indicates the relationship between forward and reflected waves. It is essentially the same as Return Loss and can be converted by a certain formula (see Return Loss section). VSWR = (1 + reflectance) / […]

S-parameters

S-parameters (Scattering Parameters) Parameters that express the mutual relationship between the magnitude and phase of input and output signals in a multiplex connection. For example, if there are two ports, it will exit from port 1 and return to port 1 […]

Regarding the definition of supported data rates for Board to Board Connectors

Regarding the definition of data rate Determined from the S parameter at differential 100Ω, the lowest value among the following is the recommended transmission speed/data rate Insertion loss = Sdd21 has sufficient linearity up to the Nyquist frequency - Do not fall below 3 dB […]
