Characteristics:This type has absorbed two 5kW combine machines plan merit, synthesis of endstage power using imported 3dB coupler. It has small size, easy maintenance, high reliability and a rational layout, adaptation mountain, high temperature and other harsh environment.RF power divider and power synthesizer use microstrip line technology. The structure packaged design are reasonable. The overall RF system uses entire wide BS design. Outputs in the entire FM frequency scope is bigger than 10KW, does not need any adjustment.In the divider and the synthesizer balance dead resistance, uses import high performance power resistor, the design remainder is big, safe and reliable.It has redundant power amplifier design of large, high safety factor, each realizes modulation, may exchange use, and uniformity is good. It is simple to maintain and insert hotly pulls out. The merit puts tube to use Dutch PHILIPS Corporation BLF278300W double MOSFET transistor, thus ensuring the overall reliability.The power unit uses switching power supply, equipped with advanced power source antiradar. When the thunder stroke appears, antiradar could rapidly be struck by lightning in the nanosecond level time leaking the voltage into the earth.Use Italian RVR Corporations PTXLCD;30;S microcomputer control type actuator, with friendly user interface, technical specifications, and easy to use man-friendly machine contact surface. Technology refers to the elevation, facilitate adjustment. The extension is conveniently strong, additional channel connection is superior, with two circuit SCA, RDS connections and so on.The control section uses digitization logic circuit, reservation remote control, and telemeter connection. It is advantageous for the user to carry on computer networking and automate transformation. Other use may request according to dispose SIEMENS liquid crystal touch screen man-machine contact surface PLC intelligence control system.The transmitter coolant conditions use forced air cooling and good dust prevention, thermostable humidity. Under the conventional condition, transmitters continuous working time is longger than 24 hours. Our company also may act according to the users demands and produce two 10kW combine 20kW all solid state FM stereo broadcasting transmitter.Descriptions and Specifications:Frequency Range: 87 ~ 108MHzFrequency Interval: 50kHzStepped Frequency: 10kHzLoad Impedance: 50ωPort Type: 3.125 inches Hard FedPower Output: ≥10KWResidual wave radiation: ≤1mW and below Carrier power 60dBPre emphasis: 50μS 75μS elects100% frequency Modulation: ±75kHzModulation largest capacity ±100kHz (m≈1)Audio 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 ≤0.3% ±100kHz; Offset ≤0.5%FM SNR: ≥70dB 1kHz, ±75kHz OffsetAM parasitic noise: ≤-50dB No modulationSubcarrier belief system: ≤-46dBOverall Efficiency: ≥68%Power Source: AC 3-phase, 4-wire 380V -10% ∼ +5%; frequency: 50Hz±1HzWhole Machine Dimensions: 1000(W)x2000(H)x1000(D)mmWeight: 900kg
