Product Description
Digital Frequency Converter 1.convert RF signal of one channel into another channel 2. low clutter interference

Product Feature
Low Power Digital Frequency Converter Outline The function of JXDH-6701 Digital Frequency Converter is to convert DVB RF signal of one channel into another channel, and it dispenses with the aftertreatment of decompressing, encoding and multiplexing to the digital signal. It can be widely applied to satellite digital TV, digital broadcast, CATV network and so on. Features * convert RF signal of one channel into another channel; * uplink-convert medium frequency into radio frequency, conversely it can; * downlink-convert radio frequency into medium frequency, besides it also can convert frequencies; * between RFs or peer frequencies; * suitable for digital signal processing as well as analogue signal processing; * LCD real-time displays various performance indexes; * Having RF automatically gain control (AGC), making front-end system working more reliably and stably; * Micro-processing unit controls input/output signal levels; * Adjacent frequency design, medium frequency processing, surface audio wave filter (SAW), good interference suppressing; * Local oscillation adopts unique phase-locked loop, low phase noise, low phase jitter, low error rate, especially suitable for digital signal frequency conversion; * Down-link frequency conversion and up-link frequency conversion adopt excellent qualified dual-balanced frequency mixer, good linearity, low distortion; * low clutter interference; * RF and medium frequency system circuits adopt multi-channel filters, which reduce outside signal interference against local machine; * RF output circuit adopts international brand amplifying module, which guarantees output dynamic and parasite suppression; * 19 standard structure, independent power supply, elegant exterior, flexible corollary equipment.

Product Specification/Models
RF Input Frenquency 30-862MHz (central frequency of an optional aptotic channel) User order guide: It is necessary to indicate the mode of RF input. A=QAM/CMTS B=QPSK; And conversion style. C=RF to IF D=IF to RF E=RF to RF For example: JXDH-6701-AE means RF input mode is QAM/CMTS and conversion style is RF to RF. RF Input Mode QAM、QPSK、CMTS (user must indicate a certain one in three modes) RF Input Level 95dBμν RF Input Level Range 85-105dBμν RF Input Impedance 75Ω Input AGC Range ±10dB/±1dB Input Return Loss ≥12dB RF Output Frequency 110-862MHz (central frequency of an optional aptotic channel) IF Input and Output Frequency 35-44MHz (125KHz Stepping) Maximum Output Level ≥115 dBμν Output Inspection -20 dBc Adjusting Range of Output Level 0-20 dB(0.5dB Stepping) Output Impedance 75Ω Output Return Loss ≥12dB Phase Noise ≥96 dBc@10KHz(30-300MHz) ≥94 dBc@10KHz(300-550MHz) ≥92 dBc@10KHz(550-860MHz) Frequency Conversion Precision ≤5 KHz Spurious Output Rejection ≥55dB(The distance of 2 contiguous frequency points>20MHz) Audio In-Band Flatness ±0.5dB General Specification Size 44mm×482mm×330mm Condition 0-45(Work);20-80(Storage) Power Supply AC110~220V±10% 50/60Hz 20VA
