Here is a simple USB FM transmitter that could be used to play audio files from an MP3 player or computer on a standard VHF FM radio by connecting it to an USB port. The circuit use no coils that have ...

The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter – an electronic device that can produce or amplify a carrier wave ...

In the first three installments of this series, we discussed whether or not an old transmitter was even worth fixing, followed by some techniques I ve used to repair high-voltage power supplies, ...

[Angelo] is only 15, but that doesn’t mean his fabrication skills are limited to Lego and K’Nex. He’s built himself an amazingly well constructed FM transmitter that’s powerful enough to be received a ...

[Dino] got his hands on an FM transmitter “bug” kit via a friend, and thought it would make for an easy and fun Hack a Week project. The kit is simple two transistor half-wave FM transmitter, which ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

A key component for these wireless battery power chargers is a power transmitter IC that offers robust, standalone applications capable of transmission distances up to 15mm and tolerance of poor coil ...

Alpha and Omega Semiconductor has released the AOZ32034AQV, a new product in the family of coil drivers for wireless charging transmitter circuits of up to 50W Packaged in a thermally enhanced QFN 4 x ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

Four new transmitter power supplies reportedly reduce costs by enabling users to construct an intrinsically safe signal circuit for SIL 3 with a single transmitter. Single-channel KCD2-STC-Ex.1ES and ...

Imec unveiled a CMOS 56Gbit/s zero-IF D-band beam-forming transmitter at the IEEE RFIC Symposium in Washington. “It is a key component of a 4-way beamforming transceiver chip currently being developed ...
