The concept of load-pull simulation is where a load or source impedance is swept by an active device and its performance is measured. Recently, advancements have been made to data file formats by load-pull measurement system vendors to expand the usefulness of load-pull characterization. These new file formats support a sweep of an independent variable such as input power, DC bias, temperature, or tone spacing, in addition to the swept source or load impedances. The NI AWR Design Environment™ software enables designers to import and manipulate these load pull data sets in a circuit simulator which greatly simplifies and speeds the design process, and gives them a broader design space to explore. This white paper covers in-depth information on how to use enhanced load-pull measurements for base station power amplifier designs.
A design house in California was looking for a network analyzer that could combine linear, nonlinear, and noise figure measurements with minimal external programming to rapidly produce statistical models of circuit and transistor performance.
Solid state amplifiers can now be constructed through the use of MMIC amplifiers to reach output powers and performance levels that have only been achievable by traveling wave tube amplifiers (TWTAs). These new high efficiency power amplifiers are designed to incorporate an antipodal finline antenna array within a coaxial waveguide that is optimized in the Ka Band. This white paper demonstrates building a 120 Watt power amplifier operating from 27 to 31 GHz through the use of a coaxial waveguide combiner structure joined with 10 Watt GaN MMIC devices.
In a world that runs on wireless devices and connections, wireless testing is increasingly important. Here is a "right-sizing" approach to managing trade-offs in testing methods and complexity to do what is necessary without breaking your budget.
You need an RF power amplifier. You have measured the power of your signal and it is not enough. You may even have decided on a power level in Watts that you think will meet your needs. Are you ready to shop for an amplifier of that wattage? With so many variations in price, size, and efficiency for amplifiers that are all rated at the same number of Watts many RF amplifier purchasers are unhappy with their selection.
The ML2437A Power Meter combines the advantages of thermal meter accuracy, diode meter speed, and peak power meter display graphics. The result is a single instrument that samples at more than 35K per second and achieves 90 dB dynamic range with a single sensor
As its model number implies, the 745-20C-T is a digital delay generator with 20 channels in one unit. It features a 100 ps time resolution (standard, with an optional 250 fs time resolution), 5 ps jitter (internal trigger), a 25 ps jitter (external trigger), 1 ns output rise times, and more.
Gopi Gampala, senior application engineer with Altair spent a few minutes with us on day two of the 2016 IMS exhibition to talk to us about their FEKO EM simulation software and the advantage of its hybridization of multiple solvers.
Choosing the right amplifier for your application isn’t as simple as looking over a datasheet. After a few decades worth of experience in RF design and applications engineering, Alan Ake with Guerilla RF has learned the intricacies of selecting the right amplifier, and now he’s sharing that information with you.
Stan Oda and Joe Mallon talked to us about one of Anritsu’s new vector network analyzers on day two of the IMS 2016 exhibition. Watch the video to learn about its features and specifications, and stick around until the end for information on its potential role for E-band antenna pattern measurements.
AR has been designing RF amplifiers since 1969, and they’ve learned a thing or two about the intricacies of high power amplifier design in that time. Their engineering manager Rob Rowe took some time out during the first day of the IMS 2016 exhibition to share some of that knowledge with you.
Selecting the wrong RF power sensor can be detrimental to the accuracy of your results, and the time it takes to get your measurements. Fortunately, Lawrence Wilson with Rohde & Schwarz is here to give you some in depth insight on what to consider when selecting a sensor to avoid such setbacks.

Peregrine Semiconductor Corp. introduces the UltraCMOS® PE19601, a monolithic phase and amplitude controller (MPAC) solution for beamforming at IMS 2016. This new MPAC–Beamforming device covers a frequency range of 8 to 12 GHz, and is designed for X-band radar applications including active electronically scanned array (AESA) weather, air-traffic control, and military radar applications.
Eastern OptX is displaying a radar target scenario generator that is designed to put a radar test range on a test bench. The Eastern OptX Series 1100 Radar Target Simulator is a true broadcasting replicator. The Series 1100 receives the signal transmitted from a radar system and adds the round-trip propagation delay associated with the target distance. That signal is then output to the radar receiver.
