AK2401A

The AK2401A is a direct conversion transceiver that provides high performance narrow-band radio communication. 
The receiver block of the AK2401A integrates a LNA, I/Q demodulator, PGA and 24-bit delta-sigma ADC, and realizes both performances of high sensitivity and high tolerance to adjacent channel interference, intermodulation and blocking. 
Digital filter that is able to support channel selection for multiple radio systems, enabling simple system designing for a radio platform. 
The AK2401A also integrates a delta-sigma Fractional-N synthesizer that composes a high performance PLL with an external VCO. The transmission block has a DAC and a driver amplifier. 
The AK2401A is housed in a small QFN package (7mm x 7mm), realizing to downsize wire-less applications.

Narrow Band Radio Communication | 6.25kHz/7.5kHz/12.5kHz/15kHz/20kHz/25kHz/ 50kHz/100kHz/150kHz / etc. 
Modulation Method | FM/2FSK/4FSK/QPSK/π/4 DQPSK /16QAM/64QAM  (Modulation / demodulation must be done externally. Modem function is not installed.)
