This is where microwave Schottky diodes were previously needed as the detector element. But their shortcomings when rectifying the RF or microwave signals when measuring only the peak of the waveform ...

He’s using an everyday LED as a detector diode and an internal pull-up resistor in the ATtiny13 for the bias voltage. The antenna runs off the LED’s anode.

The RF signal detection is made with a Schottky diode that has a low voltage on junction and is operating at a high frequency. Further, the obtained voltage is filtered and amplified with A1. Its ...

It’s not so far-fetched though, while bugs and hidden cameras in for example an Airbnb may not have flashing LEDs, they still emit RF and can be detected with a signal strength meter.

The SMS7621-096 is a low barrier silicon Schottky diode for applications including RF-power detection, video sampling circuits, and low-conversion-loss balanced mixers at frequencies up to 26 GHz.

Traditionally, microwave Schottky diodes are used as the detector element. They face serious shortcomings when rectifying the RF or microwave signals while measuring only the peak of the waveform, ...

To improve PA efficiency, designers are increasingly turning to envelope detectors. In drain modulation architectures, an envelope detector modulates the PA power supply from the incoming RF signal.

The WEA7186PD55S is a differential ended envelope detector. It has a differential input and is capable of detecting signals over a wide dynamic range, from –16dBm to 8dBm. The baseband part ... The ...

AbstractIn the article, we present a hardware meteor detector. The detection principle is based on the electromagnetic wave reflection from the ionized meteor trail in the atmosphere. The detector ...

Analog Devices has its first dual-channel radio frequency root-mean-square (rms) power detector for precision measurement of transmit and receive signals up to 2.7GHz. The AD8364 is designed to ...
