GaAs Will Remain at Forefront of Cellular Handsets

Strategy Analytics analysts, speaking at the plenary sessions of both the IEEE CSIC Symposium and the Power Amplifier Symposium, reaffirmed that GaAs technologies will continue to dominate the radio front-end in cellular handsets, despite competition from silicon technologies. The move toward 3G and beyond, coupled with the need to...

Technology Does Not Matter!

These are the words that can label you as a non-believer and a heretic. For the telecom industry, thoughts like this must be exterminated before they spread like a virus. Yet, recently an example of how little technology matters surfaced. Deutsche Telekom (DT) killed its Fixed-Mobile Convergence (FMC) service....

An Enhanced Doherty Amplifier Design Based on the Derivative Superposition Method

An enhanced 20 W Doherty amplifier with highly optimized linearity using the derivative superposition method (DSM) is proposed. DSM is a linearization technique based on the device’s transconductance characteristics. The gain compression...
High linearity and high efficiency are important design issues in a high power amplifier for base station applications in modern wireless communications. High efficiency power amplifiers, combined with high linearity, have been very desirable. The Doherty amplifier is a technique for improving the efficiency at high output power back-off....

Designing Modules for Concurrency in Multimedia Co-design

Module designs, and specifically handset power amplifier (PA) and front-end module (FEM) designs, are at a crossroads. Traditionally, the module has been an integration platform for discrete functional blocks enabled by considerable design margin, reasonable size and power constraints, and the luxury of predicted performance from cascaded analysis. Although...

An Ultra-low Noise VHF OCXO

Over the past 50 years crystal oscillators have become ubiquitous wherever a stable reference is needed in RF systems. The new Pascall OCXO has been developed to address the most critical applications where ultra-low noise is required; for example, as a reference for phase noise measurement, or as the...
