This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a preamplifier built around transistor BF200 (T2), a driver built around transistor ...

This mosfet fm transmitter circuit is designed to be used for aligning FM radio receivers. It has a microphone amplifier with automatic gain control. The FM modulation is a voltage oscillator and the ...

When shopping for an AM transmitter at any power level, the only choices from the major U.S. manufacturers are solid-state amplifiers. Choosing between solid-state versus tube for FM based on price ...

The nanoTune combines an FM transmitter, FM radio and headphone amplifier in one, and costs $69.99. The nanotune connects to the iPod nano’s dock connector and goes up its back. The features a ...

The chances are that many of you will have made an FM “bug” style transmitter ... an oscillator and buffer driving a class C power amplifier. The modulation is applied by a transistor in ...

The final stage of the transmitter may be directly modulated (in AM), or it receives an already modulated RF signal (FM). Many modern broadcast transmitters use solid-state modules in their power ...

The amplifier enlists an MRF6V2300NBR1 LDMOS ... The FM310-108 is suitable for FM transmitter, transposer, and broadcast exciter designs and versions with connectors are available upon request.

Amphony unveiled its 5.8 GHz Digital Wireless Audio Transmitter Amplifiers, Model 1520 and 1550, which are capable of transmitting audio to loudspeakers wireless and without any audio degradation.
