Directivity and VSWR Measurements - Understanding Return Loss Measurements – Marki Microwave
The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately, no directional device is perfect, leading to potentially dramatic measurement errors. This whitepaper shows that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power. Explicit expressions are derived for measurement error as a function of directivity, return loss, and reflection phase. The only accurate and convenient way to make return loss measurements is with a well-matched high directivity directional coupler or bridge. Click here for more information.
140 GHz Antenna Array for 6G Wireless Communication – Remcom
This whitepaper demonstrates the performance of an antenna array for 140 GHz wireless communication purposes, such as for use in a 6G application. The base element design consists of a TE340-mode substrate-integrated cavity (SIC) excited 2x2 slot antenna subarray in low-temperature co-fired ceramic (LTCC). The simulations are performed in XFdtd EM Simulation Software and are based on the original design. Click here for more information.
Design and Modeling of a Solid-State T/R Module for Radar Applications – Cadence Design Systems
Active phased array radars (APARs) typically require solid-state T/R modules with high-output power, low-noise figure (NF), high third-order intercept (TOI), and sufficient gain in both transmit and receive. Since the T/R module is 40-60% of the overall RF front-end cost, it is imperative to use an architecture that meets all requirements with the most cost-effective technology, such as monolithic microwave integrated circuits (MMICs), and a minimal bill of materials (BOM). Learn about various solid-state semiconductor technologies for T/R module development and a design methodology that includes the modeling/analysis of a T/R module. Click here for more information.
Total Radiated Power – Taoglas
Total Radiated Power (TRP) is a RF engineering term used to describe the sum of all power radiated by an antenna connected to a transmitter. Total Radiated Power is closely related to the efficiency of the antenna and is in fact tied to the definition of efficiency. TRP is expressed in terms of power: Watts (W), milliwatts (mW), or the logarithmic terms for W and mW (dBW and dBm). Antenna efficiency is expressed either in percentage or dB.

How to Test an RF Coaxial Cable using a Vector Network Analyzer – Copper Mountain Technologies
RF coaxial cables are high precision test assemblies, which along with a calibration kit, adapters and a torque wrench ensure the integrity of the measurements taken by test equipment such as a Vector Network Analyzer. An ideal cable transfers maximum RF energy while incurring as little loss as possible. To choose the best cable for a test solution, one has to consider several factors such as: operating frequency, characteristic impedance, insertion loss, return loss/VSWR, power handling capacity, operating temperature, flexibility, size, weight, shielding and ruggedness, with cost as a primary trade-off.

How to Design a GaN PA MMIC – PRFI Ltd.
This white paper describes how to design a custom GaN PA MMIC using a commercially available GaN-on-SiC foundry process. It uses an X-band PA requirement as the design example and runs through the design process step-by-step to the point of having a completed MMIC layout ready for manufacture. It commences with the selection of the most appropriate GaN MMIC process then moves on to transistor level simulations including load-pull analysis to determine the optimum impedances at both fundamental and harmonics. This leads to the detailed schematic design and MMIC layout methodology. Finally, the approach for performing electromagnetic (EM) simulation and layout optimisation is described.
