Testing A 24-28GHz Power Amplifier Using The 5G New Radio Test Standard
In this white paper, we will introduce some of the main challenges in test and measurement of a device at mmWave frequencies, with a 26 GHz pioneer band defined for the UK between 24.25 - 27.5 GHz.
Circuit Models For Plastic Packaged Microwave Diodes
This paper reports on the measurement and establishment of circuit models for SOT-23 and SOD-323 packaged diodes. Results indicate that the 1.5 nH estimate for the SOT-23 is a useful result, as is 1.2 nH for SOD-323 single packaged diodes. It was also determined that the effective inductance of the SOT-23 may be reduced to approximately 0.4 nH by adding a second bond wire and modifying the microstrip line. Other lead configurations, including parallel bond wires and common cathode configurations, were also studied.
Power Consumption Analysis With Specialty DC Power Supplies
Optimizing power consumption is critical for IoT devices running on small, non-rechargeable batteries. Learn how accurate characterization and smart design can extend device lifespans.
Linearity Of The JFET And MOSFET When In Saturation Over The Entire Cycle
Performing RF amplification in a way that is simultaneously linear and efficient has been a challenge in power amplifier (PA) design. Single transistor PAs can either be operated in a linear, but inefficient, current source mode of operation or as efficient, but nonlinear, switches. These techniques use two FETs, but this paper demonstrates that linear amplification can be achieved at high power with an efficiency greater than 60%, using a single FET.
Effortless Testing Of Direction Finding Devices – Amplitude Based
Together with multiple coupled R&S SMW200A vector signal generators, the R&S Pulse Sequencer allows performance characterization of all types of direction finding equipment such as devices that use amplitude comparison, interferometric or time difference of arrival (TDOA) techniques.
