Description

The AK2404 is a direct conversion transceiver IC that realizes high-performance narrowband wireless communication. The receiver section incorporates an LNA, quadrature demodulator, PGA, 24-bit ΔΣ A/D Converter, and digital filter to provide a receiver with high sensitivity and high interference tolerance without the use of ceramic or SAW filter. In particular, the blocking characteristics of Δ10MHz are over 100dB (Standard: TIA603, EN 300 0861-1). The digital filter with variable bandwidth supports channel selection for multiple different wireless systems, enabling easy system design in wireless platforms. In addition, a ΔΣ fractional N-PLL synthesizer is incorporated to configure high-performance PLLs with an external VCO. The transmitter has a built-in DAC and driver amplifier. The compact QFN Package of 8mm square contributes to the miniaturization of radio equipment.
Narrow Band Radio Communication | 6.25kHz / 7.5kHz /12.5kHz / 15kHz / 25kHz /etc.
Modulation Method | FM / 2FSK / 4FSK / π/4 DQPSK / 16QAM / 64QAM (Modulation / demodulation needs to be externally executed except the FM demodulation.)
