Four-way power divider spans 18 to 40 GHz Product News 4/1/2008 Post a comment Optimized for low insertion loss, high isolation, and amplitude and phase stability, this new power divider is well suited for electronic warfare, radar, communications systems, and test equipment
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
