Zero-in on the Best RF Transistor Technology for your Radar’s High Power Amplifier Designs

by Integra Technologies, Inc. The best solid-state, high power amplifiers (HPAs), especially those used in critical defense, aerospace, and weather-radar applications, start with the right choice of discrete or integrated RF power transistors. Several active device semiconductor technologies are available today to amplify pulsed and continuous-wave (CW) signals across narrow or wide bandwidths from HF/VHF/UHF […]

Multiband Radios for Next-Generation Wireless Base Stations

by John Oates, Analog Devices, Inc. It has been over 10 years since the smartphone revolution began, when Apple released the original iPhone® in 2007. 10 years and two generations of wireless standards later—a lot has changed. Perhaps not as glamorous as the headline grabbing consumer smartphones, known as user equipment (UE), the infrastructure base […]

Small Loop Antenna Matching for Minimum Sensitivity

by Jaakko Juntunen, Optenni Ltd. (Due to the number of images associated with this article, they are at the end of the text.) Small-size printed loop antennas are widely used in many applications such as automotive safety systems, wearables, and Internet of Things (IoT) devices. These antennas offer excellent features, including light weight, small footprint, […]

Hybrid & Electric Vehicle DC/DC Converter Design and Test Challenges

by  Mike Hawes, R&D Planning Manager for Automotive and Energy Solutions, Keysight Technologies, Inc. The latest news continues to support extensive investments and development in vehicle electrification as hybrid (HEV) and electric vehicle (EV) sales grow (Figure 1). Some of the major market constraints for EV growth are being addressed by recent EV introductions from […]

MMIC Die Testing Made Easy with Ultra-Wideband 0 dB Attenuator (Thru-line) Dice

by Radha Setty, Mini-Circuits Microwave hybrid circuitry is generally built by integrating several discrete dice via wire bonding.  Circuit designers are faced with the task of predicting the performance of hybrids, which comes with some specific challenges.  Most RF/microwave MMIC dice are built with “ground-signal-ground” bonding pads at each of the RF ports to correspond […]

New Differential Noise Figure Measurement Approach Addresses High-Frequency, High-Bandwidth Applications

by Anritsu Company The higher bandwidths and frequencies associated with many current designs, such as 5G and advanced wireless, require differential circuits and devices with improved sensitivity and low noise. Because of this, the margin for error associated with verifying differential components has narrowed considerably. Conventional methods of measuring noise figure are no longer adequate, […]

Powerful Efficient GaN Solid-State Power Amplifiers

by Heidi Thelander, Director Business Development, Comtech Xicom Technology The transformation of solid-state amplifiers for satellite communication systems from use of Gallium Arsenide (GaAs) transistors to Gallium Nitride (GaN) transistors has occurred at an astonishing rate. Not long ago, nearly all comms SSPAs were built using GaAs technology, and now it would be hard to […]
