5kW All-Solid-State FM Stereo Broadcasting Transmitter
Characteristics:The RF power distribution and power synthesizer use the microstrip line technology, the structure compact design are reasonable, without any adjustment, also the bandwidth output, easy to defend, the reliability is high.The power amplifier designs redundant quantity, high safety coefficient. Each merit puts realizes modulation, maintains simply, the merit puts tube to use import 300W double MOSFET transistor, thus guaranteed the overall reliability. The power part install the advanced power source anti-radar, when appears the thunder stroke, anti-radar could rapid be struck by lightning in the nanosecond level time leaking the voltage into the earth.The control section uses digitization logic circuit, reservation remote control, telemeter connection, s advantageous for the user to carry on the remote control and automated transformation. Other may request according to the user to dispose SIEMENS liquid crystal touching screen man-machine contact surface PLC intelligence control system.Uses the overseas famous company microcomputer control type actuator, has the friendly man-machine contact surface, technology refers to the elevation, facilitate adjustment, extension conveniently strong, additional channel connection is superior, two-circuit SCA, RDS connection and so on.This type already through the level scientific and technical payoffs appraisal, and has The State Administration of Radio Film and Television bureau product to enter the model which the net permit, the production certificate and National Wireless Communication Committee issues after due investigation to approve the card.Descriptions and Specifications :Frequency Range : 87~108MHz Frequency Interval 50kHz,Stepped Frequency 10 kHzLoad Impedance : 50ΩPort Type:1.375inches Coaxial Hard-FedPower Output : ≥5KwResidual wave radiation: ≤1mW and below Carrier power 60dBPre emphasis: 50μS, 75μS elects100percent Frequency Modulation: ±75kHz Modulation largest capacity ±100kHz m≈1Audio Input level : minus10dBm~plus10dBm OptionAudio Input Impedance: 600Ω balanced InputLeft, Right Signal Adjustment: ≤0.5dB 30Hz~15kHzLeft, right signal separation: ≥50dB 100Hz~15kHz ≥42dB 30Hz~100kHzFrequency Response : ≤±0.5dB 30Hz~15kHz,1kHz BenchmarksHarmonic Distortion: 30Hz~15kHz ±75kHz Offset ≤0.3percent ±100kHz Offset ≤0.5percentFM SNR: ≥70dB 1kHz, ±75kHz OffsetAM parasitic noise: ≤minus 50dB, No modulationSub carrier belief system: ≤minus 46dBOverall Efficiency: ≥68 percentPower Source: AC 3 phase 4 wire 380V minus 10 percent ~ plus 5 percentFrequency 50Hz±1HzWhole-Machine Dimension: 546W x 2000H x 1000DmmWeight: 450kg
High frequency drive signal has outside stirs up and local oscillation two ways, automatic cut over local oscillation when outside stirs up without signal.The overall is suitable the three phase AC 38
