HFSS developers focus on product features and new technology that deliver expanded capability with accuracy, capacity and performance. HFSS 13.0 introduces a new 3D full-wave transient field solver based on the discontinuous Galerkin method (DGTD). This finite element-based time domain solution provides engineers with an additional tool for analyzing...
The Linear Technology LTC5583 is a 40 MHz to 6 GHz dual-channel, matched RMS power detector, offering over 55 dB isolation at 2.14 GHz. In RF power amplifier (PA) applications, the LTC5583 provides a simple solution for accurately measuring forward power, reverse power and voltage standing wave ratio (VSWR)....
Hittite has developed five new wideband analog phase shifters that are designed to deliver superior performance and innovative features, all within a miniature surface-mount package. These phase shifters—HMC928LP5E, HMC929LP4E, HMC931LP4E, HMC932LP4E and HMC933LP4E—are appropriate for radar systems, satellite communications, EW receivers, amplifier linearization applications and beamforming modules from 2...
Next-generation WiMAX systems and LTE mobile data and voice systems are adopting OFDM modulation that supports a large number of subcarriers. The high peak-to-average ratio of these modulated signals causes PAs to be significantly backed off from their maximum transmit powers, thereby making the PA less efficient. To improve...
For nearly 20 years, UltraSource® has developed a sophisticated collection of thin film design solutions and modular processes that include basic single layer components for chip and wire design, integrated multilevel passives, and complex, high density, multilayer circuits. The collection of these design families and modular processes have now...
System Simulation Software ACS has recently released a new version of the LINC2 Visual System Architect (VSA) system simulation software. Version 1.10 adds a new mixer model to the VSA's components menu for enhanced modeling of mixer spur generation. Also included in this version of the VSA is a...
Low Phase Noise Assembly This integrated microwave assembly (IMA) is an example of AML's capabilities to design, test and deliver physically small multi-functional assemblies. These application specific designs offer the system designer complex functions housed in a high-density package. The illustrated product comprises a 4 W low residual phase...
Substrate Noise Coupling in Analog/RF Circuits Stephane Bronckers, Geert Van der Plas, Gerd Vandersteen and Yves Rolain Substrate noise coupling—the coupling of signals from one node to another via a substrate—is a frequent problem that occurs in integrated circuits especially where digital circuits or several analog device types are...
Radar And Antennas Download the Puzzler (PDF) Across 2 The technique used to determine ideal matching network impedances is referred to as _____________ (2 words) 6 A ___________ load-pull system has a signal input path consisting of a signal source and amplifier, source and load impedance tuners, and a...
Aeroflex Incorporated, has added new options to its ProLock 2201 Mobile Phone Test System to help service centers reduce cost with faster and more accurate testing. The WCDMA Speed and Handover upgrade (Option 2235) increases WCDMA test speed by 40 percent and adds the ability to test and perform...
