Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently. This effectively aligns with the growing ...

The mode of operation of the amplitude-modulated transmitter Class-C output stage is discussed, with particular references to the case where the load impedance varies over the working frequency band; ...

The proposed CORDIC-less digital polar transmitter demonstrates superior power added efficiency (PAE) and system efficiency (SE) for similar modulation signals. It also supports wider bandwidths, ...

Abstract: This brief presents a 120-Gb/s eight-level pulse amplitude modulation (PAM-8) 7-bit digital-to-analog converter (DAC) based transmitter with a driver current regulating technique. The output ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Tactical military radio requirements have seen significant changes over the last several years. In order to meet the communication needs of Future Combat Systems, programs like the Joint Tactical ...

The diagram utilizes two BC548 transistors, more importantly descent results although not as good as RF transistors which provide high performance at wide bandwidth. It also utilizes electret ...
