Scrambler IC for two-way radio
The AK2360A is a radio scrambler IC device suitable for half-duplex communication. As the scrambler method, a simple frequency inversion method is used in which audio signal components are inverted about the carrier frequency by using the double balanced mixer (DBM). The inverted frequency and voice passage band can be changed according to the input to the SLCT pin. The scrambler can be bypassed by using the CNT pin, and part of the circuit blocks is placed in the power-down state accordingly. A signal-to-noise ratio of 40dB or more and a distortion of 43dB or more can be obtained by inserting filters before and after DBM as shown in the block diagram, therefore allowing less sound quality deterioration when the scrambler is used.
