Features, Applications

a 1 CHIP RF IC which can be used in high performance CTO CLP systems at max. KB8528 is designed to include a receiver, PLL and COMPANDER to minimize PCB space requirements. Improved RX characteristics such as intermodulation, spurious response and ajacent channel interface have been included to satisfy the universal standards. The 1 CHIP RF IC has considerably reduced the cost by including a build-in 1'st mixer, low battery detector, fmcu, RSSI, RF requlator and speaker amp. Also, it fufills carrier detector threshold control, speaker volume control, operating mode selection and MUTE function using S/ W, thus makring external application easier. 48-QFP-1010E

FEATURES
