Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

Abstract: This paper presents the design of a RF pulse width modulator (RF-PWM) for switched-mode power amplification of varying envelope signals. The general idea is to modulate the varying envelope ...

Abstract: This paper presents a 2.4 GHz vector modulator fabricated on mechanically flexible, low-cost, environmentally friendly, celluose-based substrate. This circuit can be adopted either as a ...

The RF Building Block range is designed to provide the flexible, high performance ICs required for HF/VHF/UHF, professional radios, wireless data terminals, wireless microphones, marine and avionics ...

Operating from 30 MHz to 1 GHz, the CMX993W wideband quadrature modulator provides translation from baseband I/Q signals to a modulated RF signal. Its wideband inputs (up to 100 MHz) can be driven ...
