1.The overall gather for single channel put type entire solid state forced-air cooling design, is advantageous for the digital TV broadcast transition, the overall target conform to the GY/T177-2001 standard.2. The last stage merit put uses the LDMOS tube to enlarge technology, many merit put module unit (PA) to during a synthesis, high efficiency, small standing-wave ratio, high isolation, good work uniformity.3. LCD instructed the operational parameter, operation is simple, the man-machine contact surface is friendly, is advantageous for the maintenance and the fault judgment. The overall provides parallel connection, may realize microcomputer monitoring, telemeter and functionalizing broadcast.4.As the power amplifier used the LDMOS tube to enlarge technology, compared with the previous power amplifier has increases high, the straight characteristic good and may work in high standing-wave ratio situation and so on, suits to requirement of digital TV broadcasting.5.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.Overall Performance:Frequency Range : 470~860MHzPower Output: 1Kw Synchronous topOutput Port Type : L27Standard Load Impedance: 50Ω CoaxialImage Audio Power Ratio: 10:1Load Reflecting Loss: ≥ 26dBCooling Mode : Air CoolingPower-consumption : 2.5KWWhole-Machine Dimension : 1900mmH x 600mmW x 900mmDWeight :300kgImage part of the technical indicatorsVideo Input Voltage : 1Vpp±3dBVideo Input Impedance : 75ΩVideo Input Reflecting Loss: ≥ 34dBModulation: Amplitude modulation, NegativeImage Carrier Frequency Stability : better ±300Hz/monthGroup Delay-frequency Characteristics : 0~6MHz±30nsDifferential Gain : ±5 percentDifferential Phase : ±3 percentMarket Tilt K50: ≤2 percentBank Frequency Tilt Kb: ≤2 percent2T Sine Square Wave Distortion: ≤2 percent2T Sine Square Wave And Pulse Amplitude Rate Kpb: ≤2 percentBrightness Nonlinear : ≤5 percentBelt intermodulation distortion : ≤minus54dBSecond Harmonic Output : ≤minus60dBCyclical clutter SCR : ≥ 51dB Peak-to-peakContinuous random clutter SCR: ≥ 58dB WeightedAccompany some of the technical indicators:Audio Input: 0dBm±6dBm 600Ω balancedModulator Type: FMCarrier Frequency Stability: better ±300Hz/monthThe Biggest Frequency Partial : ±50kHz 100 percent ModulationPre-emphasis Time Constant Increase 50μsFrequency Response: ≤±1dB, 30Hz~15kHzHarmonic Distortion: ≤1 percent, 30Hz~15kHz, 100 percent ModulationFM Noise: ≤minus60dB 1kHz, 100 percent ModulationAM Noise : ≤minus50dB, no modulation
