  • Page 6 2.2.1 Overview The TK-3601D is UHF Digital transceiver designed to operate in the frequency range of 446 to 446.2MHz. The unit consists of a receiver, a transmitter, an integrated circuit of VCO/PLL, a digital control circuit, a power supply circuit, a detector circuit and a signaling circuit.
  • Page 7 2.2.3.3 RF Front-End An incoming signal from the antenna is applied to on RF amplifier (Q19) after passing through an antenna switch circuit and a 2-pole LC filter. After the signal is amplified by the RF amplifier (Q19), the signal is filtered by a 2-pole LC filter to eliminate unwanted signals before it is passed to the first mixer (Q12).
  • Page 8 2.2.3.7 Squelch and Mute Circuit The output signal from the squelch circuit includes in the FM IC (IC9), is applied to the MCU (IC7). The MCU controls the mute circuit in the audio power amplifier (IC26 or IC27). Part of the AF signal from the FM IC (IC9) enters the FM IC (IC9) again, and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level.
  • Page 9 2.2.4.6 APC Circuit The APC circuit always monitors the current flowing through the drive amplifier (Q18) and RF power amplifier (Q23), and keeps it constant. The voltage drop at R177 and R181 is caused by the current flowing through the RF final amplifier. This voltage is applied to the A/D converter in the MCU (IC7).
  • Page 10 2.2.6.2 Reset Circuit The MCU (IC7) has an integrated power-on reset (POR) / power-down reset (PDR) circuitry. However, the power-down reset (PDR) does not choose at this model. When the power is turned off, Reset IC (IC1) as 3.1V reference voltage detects that the Battery voltage fall, and then Reset IC (IC1) outputs a low level signal to the MCU (IC7).
