1 / 103 page  [AK2401] 017003093-E-00 2017/3 1 1. General Description The AK2401 is a direct conversion transceiver that provides high performance narrow-band radio communication. The receiver block of the AK2401 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 AK2401 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 AK2401 is housed in a small QFN package (7mm x 7mm), realizing to downsize wire-less applications. 2. Features Operating Frequency: 30MHz ~ 1200MHz Power Supply: 2.7 ~ 3.3V (CPVDD, DACVDD: 2.7 ~ 5.5V) Operational Temperature: -40 ~ +85ºC LNA: Gain 15dB, NF 1.2dB, IIP3 +7dBm High Linearity Direct Conversion I/Q Demodulator 24-bit ΔΣ A/D Converter: up to 150kHz Output Sampling Frequency (TCXO=19.2MHz) Band Changeable Digital Filter (Bandwidth can be set arbitrarily) Automatic Gain Control (AGC) function for LNA and PGA Real-time DC Offset Canceller (RDOC) Function RSSI Function: Data read by SPI communication 18-bit ΔΣ Fractional-N PLL Synthesizer Digital Frequency Modulation (FM/FSK) by Frequency Offset Function Fast Lock Function reduces Lock-up Time 12-bit DAC: 200kHz Max. Sampling Frequency, S/N 72dB Transmission Driver Amplifier: −6 ~ +6 dBm Output Local Signal Dividing Circuit (divide by 2 or more is recommended) TCXO Frequency: 18.432MHz / 19.2MHz are recommended Frequency: 52-pin QFN (7×7×0.85mm 0.4 mm pitch) 3. Application • Narrow Band Radio Communication: 6.25kHz/7.5kHz/12.5kHz/15kHz/20kHz/25kHz/ 50kHz/100kHz/150kHz / etc. • Modulation Method: FM/2FSK/4FSK/QPSK/ /4 DQPSK /16QAM/64QAM (Modulation / demodulation needs to be done externally. Modem function is not installed.) • Analog/Digital Dual Mode Transceiver • Digital Radio System for Industrial Use • Public safety and Community/Emergency Radio System • Convenience Transceiver • Marine/Mobile Communication System • Low power / Telemeter Transmitter • Amateur Radio System AK2401 Direct Conversion Transceiver |
