High-speed digital-to-analog converters (DACs) with high resolution in the 12- to 14-bit range enable new types of transmitter designs that employ a direct modulation scheme. In such designs, the ...

Engineering researchers have demonstrated that a longstanding theoretical method called direct antenna modulation has real-world utility for boosting the quality of radio signals when transmitting at ...

The need to expand reach in metro networking equipment designs has never been more important. With service providers trying to deliver more services with existing equipment, designers are being forced ...

Reflective Semiconductor Optical Amplifiers, also known as RSOAs, are high-performance, low-cost transceivers used for data amplification and modulation in radio over fiber systems, full-duplex optic ...

First I’ll tell what you already know. Back in the day, AM broadcasting was king and FM was commercial-free. Things changed in the 1970s as FM grew in popularity. Here we are 40+ years later with many ...
