Solutions for 802.11ad PHY Layer Testing

June 16, 2012
This application note is designed to provide you with the latest insights on enabling simulation, generation and analysis of the 802.11ad emerging IEEE standard providing Very High Throughput (VHT)—up to 7 Gbps using approximately 2 GHz of spectrum at 60 GHz over a short range.

RF Substrate Technologies for Mobile Communications

June 13, 2012
This white paper discusses a variety of RF materials and substrates capable of meeting RF Front-End module designers’ requirements. You will gain insight into how state-of-the-art expertise in substrate technology can enable the mobile devices of the next decade.

Small-Signal Intermodulation Distortion in OFDM Transmission Systems

June 13, 2012
The small-signal nonlinear distortion of a system can be described with sufficient accuracy using a third order Volterra expansion of the output in terms of the input. This simple model assumes a memoryless, frequency independent amplifier system, whereby the amplifier characteristics remain constant over the operation bandwidth or, stated equivalently, the operation bandwidth is small compared with the available amplifier system bandwidth....

RF Amplifier Output Voltage, Current, Power, and Impedance Relationship

June 13, 2012
The mismatch between these real loads and the amplifier's output impedance result in a percentage of the forward power being reflected back to the amplifier. In some cases, excessive reflected power can damage an amplifier and precautions that may affect forward power are required. This Application note highlights the major RF amplifier characteristics that impact forward power as well as net power allowing the use of Ohm's law, even when conditions are far from ideal.

Measurement of Group Delay

June 4, 2012
This application note discusses the Measurement of Group Delay and Amplitude response of RF and Microwave components and assemblies, including frequency converters, using the 6840 series Microwave System Analyzer with the Group Delay option from Aeroflex.

Leverage Circuit Envelope Simulation to Improve

June 1, 2012
Optimizing a PA design for one parameter invariably requires sacrifi cing the performance of another. This delicate balance between performance and effi ciency is not the only conundrum, because designers of 4G PAs must also contend with demands for greater instantaneous bandwidth. As a result, designers of next-generation PAs are relying on simulation more than ever before, and their tasks include frequency domain simulation, time domain simulation, and now circuit envelope simulation.

LO Harmonic Effects on TRF3705 Sideband Suppression

May 14, 2012
The LO harmonic effects on I/Q errors and sideband suppression (SBS) in the RF modulator was analyzed in application report SLWA059. This application report further investigated LO harmonic effects when attempting to achieve an increased level of SBS performance.

Statistical Analysis of Modern Communication Signals

May 14, 2012
The introduction of this digital transmission technology has made it necessary to deal with peak power levels up to 20 dB above the average value. All of the RF power components must be capable of handling these high voltage peaks to avoid break down, or flash over.

Selecting Ferrite Circulators for Radar Applications

May 14, 2012
Radar markets continue to forecast positive growth, and Skyworks Solutions offers a range of products designed specifically for these expanding markets, including materials for phase shifter applications and ferrite circulators.
