Genesys Equalize Synthesis

Genesys Equalize Synthesis quickly generates a variety of analog compensation networks that flatten group delay variations across a communication channel bandwidth, in order to reduce linear phase distortion, error vector magnitude (EVM), and uncorrected bit error rate (BER) in the underlying analog hardware.

Compensate for Linear Phase Distortion

 

Communications systems designers are concerned with many system variables, such as spur-free dynamic range, immunity to interference, AM-to-PM of the nonlinear components, and amplitude roll-off at the band edges. However, group delay ripple in the linear portions of the network, especially from aggressive, frequency-selective filtering, leads to phase distortion that is often overlooked, especially in FM and constant-envelope modulation schemes. While the effect of phase distortion is more obvious in older FM systems, it is still present in today's communications systems as a form of EVM degradation, which can affect the raw uncorrected bit error rate of the system. Genesys Equalize helps to compensate for these analog hardware issues so that the system delivers a cleaner IF or baseband signal to the signal processing front-end.

Practical linear RF circuits

 

Genesys Equalize creates a compensation circuit that is cascaded after your device under test, so that the cascaded combination minimizes group delay variation.
