ACCESSORIES: M condenser mike FM Receiver Dimension: 27cm X 17cm X10cm Weight: 500gms See Enlarge Click to Enlarge FM RECEIVER OBJECTIVE: Study of FM receiver using IC 5591. GENERAL DESCRIPTION: The TEA 5591A is a 24-pin integrated radio circuit, derived from the TEA 5591 and is designed for use in AM/FM portable radios and clock radios. The TEA5591A differs from the TEA5591A in that it has: Separate IF input pins for AM and FM A split-up AM-IF stage (for distributed selectivity) An LED driver indicator The main advantage of the TEA5591A is its ability to operate over a wide range of supply voltages (1.8 to 15V) without any loss of performance. The AM circuit incorporates: A double balance mixer A 'one-pin' oscillator with amplitude control operating in the 0.6 to 30 MHz frequency range A split-up IF amplifier A detector An AGC circuit which controls the IF amplifier and mixer. The FM circuit incorporates: An RF input amplifier An double balanced mixer A 'one-pin' oscillator Two IF amplifiers (for distributed selectivity) A quadrature demodulator for a ceramic filter Internal AFC FEATURES: LED AM/FM indicator A DC AM/FM switch facility Three separate stabilizers to enable operation over a wide range of supply (1.8 to 5V) All pins (expect pin 10) are ESD protected Each section is printed on the multi-coloured front panel for the students to understand each section thoroughly. Spring terminals are provided for interconnections. Trainer comes with multi-coloured front panel designed with the aid of C.A.D. CABINET: Trainer comes with FRP sloping cabinet for better viewing. Dimension: 41.5cms x 31.5cms x 13.5cms Weight: (Approx.) 750gms Power: 230V AC-Mains Operated See Enlarge 1 [2] [«Back ] Go to Top
