Wide Band Synthesised FM Transmitter

AS3172KT - Wide Band Synthesised FM Transmitter
Pre-Assembled and Kit versions available

Phase-Locked Loop (PLL) based crystal-locked wide band synthesised FM transmitter delivering a high quality, stable 10mW output. Accepts both MIC audio signal (10mV) and LINE input (1v p-p) for example hi-fi, CD, audio mixer (like kit 1052) or computer sound card.

The Radio Frequency (RF) output circuitry includes a three-pole filter for reduction of harmonics and other spurious signals. The spurious output signal level is better than -40dBc (0.0001 times the power of the wanted signal level), which makes the project suitable for driving an external power amplifier.

It delivers up to 10milliwatts of RF power to the antenna which can be a simple single wire about 74cm long (or open dipole or ground plane).

Ideal project for the beginner who wants to get started in the fascinating world of FM broadcasting. See documentation link below for full details (please note that the kit 3171 mentioned is no longer available).

The transmitter operates best with a 12Vdc power supply but accepts 9V to 16V. Please note that most standard DC mains adaptors are unsuitable for powering FM transmitters as they generate an unacceptable level of mains hum.

See Connectors page and Leads page for connection hardware - 778.106UK socket for power, 803.070M cable for audio input; and optional 805.805M RG58 cable for antenna (a simple wire antenna is adequate to start off).
