High efficiency in a power amplifier depends on the types of input waveforms to be boosted and typically comes at the cost of other amplifier performance parameters, such as linearity or output power.
A waveguide diplexer combines different-frequency LOs to cover a total frequency range of 275 to 500 GHz for astronomy applications.
A secure, military-grade SSD uses 256-b encryption and a rugged housing to protect sensitive data on the battlefield.
Microwave tomography was used for monitoring the condition of a human brain.
Four rapid fabrication approaches for printed circuits were compared in the production of RFID tag antennas for the European and U.S. frequency standards.
Frequency conversion at higher frequencies will be a necessary part of emerging 5G systems, requiring low-noise signal sources to start the frequency-mixing process.
Learning how to calculate the phase center of an antenna can simplify the positioning of antennas in communications links.
In this article, the design of second-order tunable lumped-element bandpass filters is considered with special attention given to circuit topology. Closed-form design equations are provided.
“Shape-memory” alloys can function as light-weight, miniature actuators on board smaller satellites.
This fourth and final post in a series on oscillators examines the voltage-controlled crystal oscillator.
