  • Page 20 SA-HT640WPL 8.2.1. Operation RF signal transmission and reception: During the receive process, the radio signal is taken from a pair of balanced RF I/O pins that feed into the low noise amplifier (LNA). Direct I/Q down conversion and on-chip filtering send the processed I/Q data to the analog-to-digital converter before processing by the GFSK (Gaussian Frequency Shift Keying) demodulator.
  • Page 21 SA-HT640WPL Does the system support any mode to save power consumption? Yes, it has POWER SAVING SCAN mode. When the communication link is lost, the slave starts scanning procedure to re-establish the link. If the slave cannot find the master within a certain amount of time (info stored in EEPROM), the slave automatically goes into power saving scan mode.
  • Page 22 SA-HT640WPL How can Master or Slave setting be selected? By software or hardware? It can be selected by external control pin. How long does it take to transmit single packet? To establish communication channel properly, hopping frequency and Syncword of each packet should be determined by Device ID(Identification).

  • Page 23: Class-D Amplifier

    SA-HT640WPL 8.3. Class-D Amplifier 8.3.1. How are digital amplifiers different? A digital amplifier incorporates a switching output stage that operates according to a principle known as pulse width modulation (PWM). In contrast to the low-frequency control signal used in a conventional analog amplifier output stage, the switching output stage of a digital amplifier is controlled by a high-frequency digital signal.
  • Page 24 SA-HT640WPL 8.3.5. What are the potential problems of a Class-D amplifier based system? The two most common issues of class-D amp system are AM interference and EMI. The switching frequency of class-D ranges from 300kHz to 450kHz typically 315kHz. The harmonics of such switching frequency will fall into the AM band of 600kHz to 1710kHz.
  • Page 25 SA-HT640WPL Class-D amp systems are basically switching systems. As such, it is prone to EMI. EMI issues can be rectified through proper grounding techniques and proper components layout. It is quite common to see ferrite beads, capacitors and inductors on these systems.
