SAW Voltage-controlled Oscillators

Presentation of applications that use voltage-controlled surface acoustic wave oscillator technology to provide high performance telecom solutions
Voltage-controlled surface acoustic wave (SAW) oscillators (VCSO) have been used for many years in both commercial and military applications. The low phase noise allows frequency multiplication to higher frequencies for use as sources, such as local oscillators in radar and other microwave systems. The excellent tuning linearity provides outstanding...

Optimizing Link Performance, Cost and Interchangeability by Predicting Residual BER: Part II - Nonlinearity and System Budgeting

This is the second part of a two-part tutorial on residual BER prediction for cost optimization of oscillator phase noise and power amplifier linearity. Today’s demanding digital modulations require a different type of analysis at ‘normal’ receive powe...
In part I, the economic case from the network operator’s perspective was reviewed and it was found that as operators improve their residual BER performance, their market space is expanded from simple voice applications to e-commerce transactions and other data traffic which demands ultra low error rates. Next, the...
