Description
KT0623 is one of product series of revolutionary wireless microphone chip family--KT06xx. Compared to the traditional solution, this product solution can save hundreds of electronic devices and maintain a high level of sound quality and functionality.
KT0623 is a UHF band transmitter chip, integrated with built-in audio amplifier, pre-emphasis filter, compressor, phase locked loop and programmable power amplifier. KT0623 uses frequency modulation to transmit the audio signal of the microphone and works in the UHF band.
KT0623 only needs a low-voltage power supply because of its built-in voltage regulator. Using KT0623 to design products can avoid tedious external debugging and save a lot of development investment.
KT0623 only needs a simple circuit to achieve mechanized tuning, and it can also use low-cost EEPROM to configure radio settings and meet the individual needs of customers. No MCU is needed, and its package is QFN24.
