AK2347B Datasheet Two-way Radio Audio & Sub-audio Processor

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: ASAHI KASEI [AK2347B] AK2347B Two-way Radio Audio & Sub-Audio Processor 1.

General Description

AK2347B includes audio filter, limiter, splatter filter, pandor, scrambler, 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
