AKM IFBPF Technology

AKM IFBPF Technology
(AK2364, AK2365A, AK2400)

AKM unique analog filter design technology enables integrated narrowband channel filter with high selectivity.

Feature

Eliminates external IF ceramic filter

⇒ "minimize PCB area" and "improve drop impact resistance"

Two-way Radio ICs
Feature

Selectable filter bandwidth by register control

⇒ BPF_BW=±10kHz/±7.5kHz/±6kHz/±4.5kHz (AK2364)
±7.5kHz/±6kHz/±4.5kHz/±3kHz/±2kHz (AK2365A)

Digital Frequendy Modulation

Frequency offset function

AK2400 and AK2401 have the frequency offset function, which enables glitch free frequency transition by register setting.
This function enables Digital Frequency Modulation for FM/FSK applications and Auto Frequency Correction.
AK2400 and AK2401 contributes to minimize PCB area and lower cost by replacing conventional modulation system in which variable-capacitors and other discrete components are used.

Two-way Radio ICs

DFM evaluation kit

AK2400 and AK2401 evaluation kit prepares the user interface based on narrowband wireless standards such as ARIB STD-T98.
The kit simplifies user’s evaluation using pseudo random pattern or arbitrary data.
