Find The Right Channels With Switch Filter Banks

Switches and filters are electronic components used in many RF/microwave systems, such as transmitters and receivers. Each provides functionality to aid high-frequency systems, but the functions can also be combined into switch filter banks to save size, weight, and power (SWaP) when miniaturizing a system.

Reliability Comparison Of 28 V – 50 V GaN-on-SiC S-Band And X-Band Technologies

This paper discusses the reliability performance of Wolfspeed GaN/AlGaN high electron mobility transistor (HEMT) MMIC released process technologies, fabricated on 100 mm high-purity semi-insulating (HPSI) 4H-SiC substrates.

MRSE-5000 Family Of EW Emulators

D-TA’s Multichannel Radar Signal Emulator (MRSE) solution is based on the concept of streaming I/Q data from deep memories (computer hard drives). As a result, the MRSE family of EW emulators are the only ones in the market that can create a true electromagnetic operational environment, not just radar pulses.
