An Eight-channel YIG-tuned Frequency Synthesizer Array

Development of a new YIG-based frequency synthesizer array that provides up to eight independent frequency channels
Product Feature An Eight-channel YIG-tuned Frequency Synthesizer Array Micro Lambda Wireless Inc. Fremont, CA Low phase noise is a staple of modern communication systems signal sources. For that reason system designers prefer yttrium iron garnet (YIG)-based sources. In addition, many of today's communications systems are required to operate at...

Gain for Compressed Amplifiers

Examination of two approaches to the concept of gain, differential and ratiometric in compressed amplifiers
Tutorial Gain for Compressed Amplifiers There is growing interest in operating amplifiers into compression to achieve higher power-conversion efficiencies. It becomes constructive then to revisit the concept of amplifier gain, because when an amplifier operates in compression the general assumption that the output signal is directly proportional to the...
