UNUSUAL TELEPHONE APPLICATIONS TDA1083 - PRINTED PLATE

Producer: AVT

Transceiver systems, especially on available and cheap integrated circuits, are very popular. Its renaissance experiences the TDA 1083 cube. On the basis of this system, you can make a number of interesting and useful radio systems. Inside the structure are: IF amplifier, AM oscillator, AM mixer, AM / FM demodulator and a MW amplifier. This allows you to do, among others FM receiver, CW / SSB receiver with direct frequency conversion, CW / SSB track with intermediate frequency conversion, SSB filter exciter. All these systems can be assembled on one printed circuit board. It contains all the necessary connections - their choice depends on the specific scheme.

The device is especially recommended for radio amateurs and amateur radio players

Selected parameters:

• a printed circuit board on which four different systems can be assembled
• power output of the MW amplifier 300 mW
• total power dissipated at 600 mW
• power supply - 5 Vdc
• printed circuit board and documentation included
