AK2346B Datasheet Two-way Radio Audio Processor

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: ASAHI KASEI [AK2346B] AK2346B Two-way Radio Audio Processor 1.

General Description

AK2346B includes audio filter, limiter, splatter filter, PANDOR, 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 ponents.

Key Features

  • Audio processing.
  • TX and RX amplifier.
  • Pre/De-emphasis circuit.
  • Compressor and Expander with no external components.
  • Scrambler and De-scrambler in frequency inversion type.
  • Limiter with level adjuster.
  • Splatter filter for wide and narrow band.
  • Digital controlled amplifier for microphone, modulator and demodulator sensitivity.
  • 1200/2400bps MSK MODEM with frame detection.
  • Wide range operation voltage: 1.9V t.
