  • Page 13: Circuit Description

    2.5.1 Overview The NXR-1800 is a UHF Analog FM & Digital repeater operating in the 400~470MHz (E2 type), or 450~520MHz (E type) range. Transmit RF power range is 1W to 40W adjustable. The unit consists of receiver circuit, transmitter circuit, phase-locked loop (PLL) frequency synthesizer circuit, digital and audio control circuit, display circuit, and power supply circuit.
  • Page 14 2.5.3 Receiver System 2.5.3.1 RF circuit The receive signal from RX ANT is amplified by a RF amplifier (LNA: IC703) and passes through the variable capacitor tuned band- pass filters (BPF) to attenuate unwanted signals. The signal passing the band-pass filters (BPF) is heterodyned by the first mixer (RX 1st MIX: IC702) with the first local oscillator signal from the RX PLL frequency synthesizer circuit to produce a 45.00 MHz first intermediate frequency signal (first IF signal).
  • Page 15 2.5.4.4 CM Coupler circuit CM coupler circuit is a line for detecting forward wave and reflected wave. Forward wave is detected by IC3027 and is converted into DC voltage. If an abnormal antenna load is connected, reflected wave is detected by D3081 and converted into DC voltage. 2.5.4.5 Filter circuit This circuit is removes harmonics from the transmitter output and sends filtered signal to the antenna.
  • Page 16 2.5.5.3 TX VCO/ TX PLL 2.5.5.3.1 VCO circuit TX VCO consists of two VCOs, TX_L VCO and TX_H VCO. TX_L VCO and TX_H VCO are switched by DC switches (DC SW: Q2008 and Q2009), according to the operating frequency. TX VCO generates the carrier for the transmitter and the frequency range is 400 to 470MHz (E2 type), or 450 to 520MHz (E type). TX_L VCO (Q2003) oscillation frequency range is 400 to 435MHz (E2 type), or 450 to 485MHz (E type), and TX_H VCO (Q2007) is 435 to 470MHz (E2 type), or 485 to 520MHz (E type).
  • Page 17 2.5.6 Control Circuit The control circuit mainly consists of MPU/DSP (IC33) and FPGA (IC60) and their peripheral circuits. Furthermore, IC33 is composed of an ARM processor based on ARM Cortex-A15 and a DSP based on C66x. Their main tasks are as follows. (1) The MPU manages the operation of the Repeater and the external interface.

The MPU/DSP controls the flash memory, DDR3, eMMC, FPGA, and various control circuits.
  • Page 19 2.5.6.5 ADC, DAC circuit The ADC/DAC circuit consists of an ADC (IC76) and DAC (IC77 and IC78). The ADC/DAC performs the following processes: DAC: Conversion of various RF control voltages from digital to analog. ADC: Conversion of power supply voltage and various temperatures from analog to digital. 2.5.6.6 This repeater is equipped with a 100Base-TX or 10Base-T LAN interface.
