Page ofModel: FRS101 (DX-6221US) Reasearch and Development Department 3 16 CIRCUIT DESCRIPTION Circuit Composition and Operation Theory The basic explanation for the circuit composition of FRS101 consist mainly of the one board controlling the analog circuit parts and the digital circuit parts for the other control. RECEIVER FRS101 transmission parts is composed in the double conversion system, which has the 1st IF frequency of double 21.7 MHz and the 2nd IF frequency of 450 MHz. With the RF front-end which has an excellent band characteristics and skirt characteristics, the 2 pole MCF used in the 1st IF, and the 3 pole ceramic filter in the 2nd IF, the reception interrupting factors such as the image and the sensitivity repression are reduced for the more stable reception. RF Front-end The signal received by the antenna will be transmitted to the band pass filter through the antenna switching circuit consisted of CT20, LT4, LT7. The front RF amplifier transistor QR1 consists of the LR5, LR6, CR71, CR72, CR81 input band pass filter and LR2, LR3, CR2, CR7, CR16 output band pass filter, primarily diminishes the other signal rather than the 1st IF image and other signal within the reception band and amplifies only the necessary signal within the RF. 1st Mixer The receiver which has been amplifier in the RF frontend is provided to thebase of the 1st mixer QR2. The 1st L/O signal provide from the VCO is supplied to the emitter of Q2 and converted to the 1st IF21.7 MHz. 1st IF Filter and 1st IF Amplifier The signal recovered by QR2 to 21.7 MHz, the 1st frequency, change its impedance through C43, L6 and then is infused to the fundamental MCF which has the center frequency of 21.7 MHz and the width of +/-3.75 KHz. Here, the signal reduces the image and other unwanted signal for the 2nd IF, and changes its impedance again through the RR11. Then signal is infused to QR3, the 1st IF Amplifier. The signal infused to the QR3 is amplified approximately by 20dB in order to acquire the required reception sensitivity, and infused to the IC1 which functions as the 2nd mixer, the 2nd IF amplifier, and the FM detector. 2nd Mixer, and IF, FM Detector (IC101) The received IF signal of 21.7 MHz, which has been infused to IC1 is mixed with the 2nd L/O converted to 450KHz, the 2nd IF frequency. The receiver signal converted to the 2nd IF signal frequency passed through the CF2, the ceramic filter of 450 KHz again. After the limiting inside the IC1 and the FM demodulating by the quadrature detector inside the IC1, the signal offers the output through the 9th oin of IC1. The squelch circuit is composed to detect the noises from the received signal demodulated in the 9th pin of the IC1. For this purpose, the noise filter is using the OP amplifier inside the IC1. Dec 27, 2001 SHENZHEN DAXIAN DIGITAL TELECOMMUNICATIONS LTD. Page ofModel: FRS101 (DX-6221US) Reasearch and Development Department 4 16 Audio Power Amplifier (IC102) The received audio signal, which has been filtered by U4, U5 and adjusted to the appropriate volume by MCU, QR5, QR6, QR7 supplied to the 4th pin of the U6 and amplified approximately by 20dB. Then, it turns up the speaker with the maximum output of 1000mV. The 1st pin of U6 is the speaker power control. If a voltage supply to the 1st pin of U6 is supplied to this terminal, the U6 stops functioning as the audio power amplifier regardless of the signal supplied to the 4th pin of U6, and there is no sound can hear from the spaker. TRANSMITTER Pre-emphasis(U5) The voice signal input from the microphone is pre-emphasized at the U5C. The signal which comes out of the U5A is limited to a certain amplitude for the voice signal not to exceed the allowable bandwidth assigned for transmission. TXPower(QT3) The transmitted signal of approximately 7mW, combined at the driver TR is supplied to the base of QT3 amplifier. The transmitted signal amplifier to 0.4 W here passes the TX LPF of the 2nd characteristics of the LT4and LT5, and RX/TX switching takes place by DT2. After this, the signal is provided to the antenna through thr TX LPF of the 1st characteristics consisted of the LT10. "FRS' FREQUENCY SYNTHEIZER Voltage Control Oscillator (VCO) The VCO oscillates 462.5625 MHz to 467.7125 MHz under the transmission condition and 440.8625 MHz to 446.3125 MHz under the reception condition. The RX/TX VCO consist of the oscillator of the QT13, LT13, DT10, DT11 and QS12. VCO should oscillate relatively low frequency during reception compared to transmission, the DT10 is biased by the QS12. Therefore as a result, the C232 is added in parallel to the resonance circuit of the VCO to oscillate a low frequency. During transmission, a relatively high frequency should oscillate compared to reception. Therefore, the DT is adversely biased by the QT10, and as aresult, the C232 which is added unparalled to the circuit of the VCO is removed to oscillate the desired transmission frequency. The VCO is controlled by the IC4 PLL IC in order to oscillate accurate fre…
