Quantifying system performance of GSM/GPRS PAs with differing levels of integration
Oct 1, 2004
By Mendy Ouzillou The two key power amplifier metrics are power and efficiency. When comparing
power amps with different levels of integration, the context of how the
specifications are defined is important. The performance of the system solution
is referenced to the antenna and battery, then distilled into one metric....
Effective Cascaded Intermodulation Analysis
Sep 1, 2004
By Rulon VanDyke A new simulation technique has been developed that empowers designers
to maximize intermodulation and noise performance while reducing analysis
time. Complicated, individualized, custom spreadsheets, math packages and ad
hoc tools are prone to error and unnecessary. This new simulation technique
leads to better designs, a quicker design phase and more revenue for the
company....
