LA1140数据手册RF/IF射频/中频RFID的RFIC模块规格书PDF

描述 Description

LA1140 is an IF system IC with quadrature detection designed for FM car stereo receivers. It features versatile muting characteristics and allows receiver designers to realize the muting performance according to their design concept. Since the muting characteristics can be varied with a switch or a semi-fixed resistor, DX-Local switching will be accomplished with ease.

特性 Features

• Versatile muting
• High limiting sensitivity (25 dB typ. with muting off)provides a fine quieting characteristic
• High S/N (78 dB typ.)
• Low distortion (0.05% typ.) avaiable if used with double-tuned circuits
• Good AMR (63 dB typ. with 6 stages of differential IF amplifiers).
• Signal meter drive output proportional to the input signal strength in dB (suitable to control multiplex IC LA3370).
