Introduction
AK2346B includes audio filter, limiter, splatter filter, COMPANDOR, sCrambler, MSK MODEM, which is highly integrated two-way radio baseband functions for FRS and LMR. Audio high-pass filter shows a high attenuation in magnitude response characteristics under 250Hz that supports to eliminate a subaudio tone clearly. TX limiter for deviation control has a limiting level adjuster by applying a DC voltage via external components. Splatter filter has the magnitude response for narrowband( fc=2.55kHz) and wideband(3.0kHz) to meet various regulatory agencies in the world wide. COMPANDOR is no adjustment type because it includes all parametric components inside the chip. Scrambler circuit is composed of frequency inversion circuit by double balanced mixer that has 3.388kHz carrier clock. MSK MODEM for data communication can be chosen either 2400bps or 1200bps. 2400bps data rate provides a high speed data transmission and 1200bps supports a low BER(bit error rate) performance that is suitable for under weak electrical field condition application. There are four signal level adjusters for microphone, modulator and demodulator sensitivity by digital controled amplifier (volume).
