Understanding Antenna Gain, Beamwidth, And Directivity
Antenna gain affects, or is affected by, bandwidth, directivity, power, and frequency in oft-misunderstood ways that can differ across antenna types.
Almost every RF test setup requires connectors and cables. Connectors will influence test results in various and sometimes unpredictable ways. Test equipment can compensate for some of these influences but often with detrimental effects. This article discusses how the connections used in a test setup will affect test results and why it is important to create a valid test environment.
This white paper describes the design and simulation of a complete downconverter module for use in spectrum analyzer test equipment. The example module and its constituent parts were designed and simulated with AWR Design Environment software demonstrating a top-down/bottom-up approach using circuit- and system-level analyses. The integration of the downconverter within a mechanical outline influences the layout of the individual radio blocks. Electromagnetic (EM) simulation of the module housing along with these blocks is necessary to produce a comprehensive analysis of the manufactured module.
Microwave bandpass filters are the fundamental component used in many RF/microwave applications to eliminate interference from signals operating at nearby frequencies. This application note presents a straightforward and largely nonmathematical method for designing an edge-coupled, bandpass filter for X-band operations with a combination of filter synthesis, closed-form edge-coupled transmission-line models, and EM analysis using the Microwave Office circuit simulator within Cadence AWR Design Environment software.
Custom transmitters and receivers for radar simulation systems enable unique designs and allow designers to meet specifications unattainable using off-the-shelf components.
Rohde & Schwarz's CLG cable load generator is a multichannel signal generator for cable TV signals that operates in the 47 MHz to 1002 MHz frequency range. It features up to 119 channels for European cable television, and up to 158 channels for US cable television. Users are able to simulate any possible channel loading scenario in the lab due to the CLG’s ability to generate freely combined digital and analog TV signals.
