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"
[Feature]
Selectable filter bandwidth by register control
⇒ BPF_BW=±10kHz/±7.5kHz/±6kHz/±4.5kHz (AK2364)
±7.5kHz/±6kHz/±4.5kHz/±3kHz/±2kHz (AK2365A)
[Feature]
Very small temperature drift and device variation of frequency
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.
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.
Direct Conversion Receiver
Direct Conversion Rx/Tx
(AK2401, AK2403)
AKM is pursuing design flexibility and PCB area conservation for the two-way radio market. The direct conversion architecture receiver/transmitter ICs will be available soon supporting multi standard from 6.25KHz to 150KHz channel bandwidth.
Direct Conversion Receiver
AK2401
[Feature]
AKM’s master design DC offset cancellation technique “RDOC”
(Real-time DC Offset Canceller)
⇒ AKM has newly developed RDOC function which enables Zero-IF receiver structure even in narrowband communication. The operation is automatically performed on chip requiring no DSP programming.
[Feature]
Embedded “Programmable digital channel filter” enables “common platform” which supports multiple standard
Example of supported standards:
TIA-603/EN 300 086-1/DMR/dPMR/NXDN/ARIB STD-T98/ARIB STD-T102/APCO P25/TETRA
Cartesian Feedback Loop Transmitter
Cartesian Feedback Loop Transmitter
AK2403
AK2403 achieves high linearity using Cartesian Feedback Loop and contributes to minimize PCB area and reduce BOM cost by integrating DAC, Fractional-N synthesizer and VCO.
[Feature]
Achieving high lineartiy using Cartesian Feedback Loop
