  • Page 15 2.4.1 Overview The NX-5800 is a UHF Analog FM & Digital Mobile transceiver designed to operate in the frequency range of 450 to 520MHz (F, K) or 380 to 470MHz (F2, K2). The unit consists of a receiver, a transmitter, a phase-locked loop (PLL) frequency synthesizer, a digital control unit, and a power supply circuit.
  • Page 16 2.4.4 Transmitter System 2.4.4.1 Audio Band Circuit The signal from microphone is amplified and converted to digital signal by IC902. IC902 includes AGC function. Digital signal is transferred to IC706 thru SSI. 2.4.4.2 Base Band Circuit The audio signal transferred from IC902 is processed at IC706. Voice signals of 300Hz or lower and frequencies of 3kHz or higher are cut off and an audio range 300Hz to 3kHz is extracted.
  • Page 17 2.4.5.2 There are TX VCO and RX VCO. The TX VCO (Q107) generates the carrier for the transmitter. The VCO oscillation frequency range is 450 to 520MHz (F, K) or 380 to 470MHz (F2, K2). The transmit frequency range is 450 to 520MHz (F, K) or 380 to 470MHz (F2, K2). The RX VCO (Q105) generates the 1st local signal for the receiver.
  • Page 18 2.4.6.5 The DSP circuit consists of a MPU/DSP (IC706) and processes the baseband signal. The DSP operates at 288MHz (MAX) clock, the I/O section operates at 3.3V/1.8V and the core section operates at 1.2V. The DSP carries out the following processes: •...
