The testing and troubleshooting of high power and high frequency systems such as distributed antenna systems (DAS), base stations, and various radar applications require buffering to prevent a power overload to the testing equipment and sensitive subsystem internal circuitry. With powers as high as 60 dBm (1000 Watts), radio frequency (RF) terminations and attenuators are … [Read more...]
Avionics Thermal Management of Airborne Electronic Equipment, 50 Years Later
BACKGROUND In a proposal submitted to the Air Force in November of 1968, Collins Radio Company described ways to improve the electronic industry’s understanding of thermal management and predictive techniques [1]. This article briefly describes that proposal and discusses what aspects of electronics cooling have changed over the past five decades and what things have … [Read more...]
Enhanced Power Cycling Thermoelectric Modules Provide 1 Million Temperature Cycles
Global technology leader Laird has improved its advanced PC Series Power Cycling thermoelectric module (TEM) for applications that require high reliability and high volume thermal cycling between multiple temperature set points. The enhanced PC Series is now proven to perform more than 1-million temperature cycles, extending the mean time between failure (MTBF) in molecular … [Read more...]
Custom Liquid Cooling Systems Optimize Particle Accelerators Performance
Global technology leader Laird has developed self-contained liquid cooling systems (LCS) that deliver optimal temperature stabilization for more precise temperature control in particle accelerators like linear accelerators (LINACs) and cyclotron systems. LINACs and cyclotrons increase the kinetic energy of particles for use in a variety of applications, ranging from scientific … [Read more...]
