  • Page 13: Circuit Description

    2.5.1 Overview The NXR-1700 is a VHF Analog FM & Digital repeater operating in the 136~174MHz range. Transmit RF power range is 1W to 50W 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 2.5.4.5 Filter circuit This circuit is removes harmonics from the transmitter output and sends filtered signal to the antenna. 2.5.4.6 APC circuit The automatic transmission power control (APC) circuit stabilizes the transmitter output power at a pre-determined level. The forward RF signal from CM coupler circuit is detected to FWD DC voltage by PA control (PA CTL: IC3027) and fed to DC amplifier (DC AMP: IC3026 (2/2)).
  • 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 136 to 174MHz. TX_L VCO (Q2003) oscillation frequency range is 136MHz to 155MHz, and TX_H VCO (Q2007) is 155MHz to 174MHz.
