    5.1 GENERAL TRANSCEIVER DESCRIPTION 5.1.1 INTRODUCTION The E.F. Johnson 4300 is a microcontroller-based radio that uses a Digital Signal Processor (DSP) to provide the following modes of operation: Narrowband Analog - FM modulation with a maximum deviation of 2.5 kHz. This mode is usually used in systems where the channel spacing is 12.5 kHz.

  • Page 45: Circuit Protection (Fuses)

    5.1.3 CIRCUIT PROTECTION (FUSES) Circuit protection is provided as follows: • An 8- or 10-ampere fuse in the power cable provides overall transceiver protection. • A 2-ampere fuse on the RF board protects circuits on that board. • F700 (2-ampere) on the display controller board protects the Sw B+ output of the microphone connector.

    In Project 25 Digital Mode, the carrier is modulated with four discrete deviation levels. These levels are ± 600 Hz and ± 1800 Hz. Digitized voice is created using an IMBE™ vocoder. (IMBE™ voice coding technology embodied in this product is protected by intellectual property rights including patent rights of Digital Voice Systems, Inc.)

  • Page 47 Front End LNA and Bypass Switching The Low Noise Amplifier (LNA) is critical in determining the overall noise figure of the receiver chain. An MGA-71543 amplifier (U39) provides optimum noise figure, gain, intercept point, and power consumption. Post-LNA Bandpass Filters An additional bandpass filter is located after the LNA.

  • Page 48: Synthesizer

    A two-pole 64.455 MHz crystal filter (U2) is used to provide the desired level of adjacent channel rejection while providing minimal amplitude and phase distortion within a 25 KHz bandwidth. Shields are installed around the crystal filter to provide sufficient isolation to meet the second image response specifications and to minimize noise pickup by the impedance-matching inductors (L1, L2, L3, L4 and L7.) A transistor IF amplifier (Q1) and supporting circuitry is required to boost the signal...

  • Page 49: Transmitter

    The transmit PLL phase locks a transmit oscillator that is operating at an output frequency of 138 to 174 MHz. The RF signal into the PLL chip is created by mixing the transmit frequency with the receive PLL frequency to generate a mix frequency of 374.4 MHz. This provides low frequency modulation of the VCO by modulating the transmit PLL reference frequency.

  • Page 50: Vhf 20-Watt Pa Board

    The power amplifier (U3) is a Mitsubishi RA07M1317M module. This PA module provides the desired RF power output level and is stable over a wide range of VSWR conditions. The PA is driven by a SGA-6589 driver (U20) that typically provides +21 dBm output power. The PA is turned on and off by switching the power to this driver via transistor D10.
