Abstract: A new kind of RF solid-state oscillator design is observed. The oscillator has two feedback loops, which provide a safe working condition for the power transistor at high levels of RF output ...

This project focuses on designing and implementing a high-frequency oscillator tuned to 3.5 GHz for enhancing transmitter antenna performance. It integrates RF engineering, microwave engineering, and ...

Abstract: A novel microwave sensing system based on a feedback-type RF oscillator and modified magnetic-LC (M-MLC) resonator is proposed in this article. The M-MLC-based passive sensor has evolved ...

A current-feedback amplifier is a well-known component with many uses. Its basic block diagram shows that its input stage is a voltage follower—in practice, a symmetrical emitter follower (Figure 1).

Thanks to its low jitter and excellent phase noise, the RFX300 radio-frequency crystal oscillator is well suited for Sonet, synchronous digital hierarchy, asynchronous transfer mode, and wireless-area ...

Designers often choose a super-regenerative receiver—despite its frequency instability and poor selectivity—for battery-powered, short-range, wireless applications in which power consumption is a ...

In this communication we report the construction of a printed circuit board which mounts directly to the vacuum chamber of a mass spectrometer and produces the RF waveforms needed by many ...

There are plenty of hobbies around with huge price tags, and ham radio can certainly be one of them. Experienced hams might have radios that cost thousands of dollars, with huge, steerable antennas on ...

Imperial College is developing an implantable passive blood pressure monitor based around a SAW (surface acoustic wave) oscillator. “In essence, it is an oscillator that you can ping from the outside ...
