Flesh out your RF/Microwave bookshelf RF & Microwave Designline Blog 9/22/2010 1 comment I just heard from my contacts over at SciTech Publishing that they are having a clearance sale on some of their RF and Microwave titles. If you are looking to flesh out your bookshelf, now might be a good time.
RMS detector protects basestation PAs Product News 9/9/2010 1 comment Linear Technology just released its model LTC5583, a 40MHz to 6GHz dual-channel, matched RMS power detector that seems exceptionally well suited to monitor VSWR in a basestation transmitter RF power amplifier (PA).
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.
