Novel Passivation Ledge Monitor in an InGaP HBT Process

The HBT ledge thickness and quality is vital for device performance and reliability. In this work we report on a measurement technique and test structure for monitoring the emitter passivation ledge based on the use of TaN as a barrier between the InGaP ledge surface and the top metal contact.

A 5 GHz 0.95 dB NF Highly Linear Cascode Floating-Body LNA in 180 nm SOI CMOS Technology

High data rate wireless local area networks (LAN) have fueled the rapid growth of portable electronics. To keep the overall solution cost of portable devices low, the wireless transceiver should be highly integrated with the baseband as a system-on-chip (SoC) solution, preferably using a low-complexity CMOS process.

Designing Flexible Software-Defined Radio Architectures

High-performance communications systems utilize digital baseband signal processing, where very little of the signal processing is performed in the analog/RF domain. Such signal processing includes filtering, phase/frequency de-rotation, channel equalization, pulse shaping, and modulation/demodulation. When sampling rates and numeric precision are accounted for, digital signal processing provides ideal functionality.

Designing Ultra Low Noise Amplifiers for Infrastructure Receiver Applications

Amplifiers used in wireless infrastructure receiver applications have the key requirements of low noise, high linearity, and unconditional stability. In order to meet these needs, Skyworks has developed a new family of low noise amplifiers (LNAs) implemented in 0.5 μm enhancement mode (E-Mode) pHEMT.

Choosing the Right RF Switches for Smart Mobile Device Applications

Modern smartphones and tablet computers typically incorporate multiple wireless services at different frequency bands ranging from FM radio to LTE. At the same time, an increasing number of designs utilize more than one antenna to enhance sensitivity and suppress cross-talk.

Basics of Dual Fractional-N Synthesizers/PLLs

The term fractional-N describes a family of synthesizers that allow the minimum frequency step to be a fraction of the reference frequency. Over the years, a number of methods have been proposed to realize fractional-N frequency synthesis that are based on the basic concepts of traditional integer-N synthesis.
