ST-AC002 天线耦合板

DescriptionThe Si21622C integrates two separate high-performance digital demodulators for the DVB-T2/T, and DVB-C2/C standards into a single compact package. Leveraging Skyworks' proven digital demodulation architecture, the Si21622C achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si21622C to a dual terrestrial/cable TV tuner results in a high-performance and cost optimized TV front-end solution.Skyworks' internally developed DVB-C2 demodulator can accept a standard IF (36MHz) or low-IF input (differential) and support all modes specified by the DVB-C2 standard. The main features of the DVB-C2 mode are 4096-QAM, 6 or 8MHz bandwidth, management of notch insertion (broadband and narrowband), and support of multiple data slices and PLPs.DVB-T2 (including T2-Lite) demodulators support all modes specified by the DVB-T2 standard (V1.4.1). Main features of the DVB-T2 mode are, SISO and MISO support, FEF management, fully autonomous signal acquisition including automatic L1 signaling parsing support for all pilot patterns, and DVB-T2/T auto-detection. The DVB-T and DVB-C, including ITU-T J.83 annex B, demodulators are enhanced versions of proven and broadly used Si2164/67/68/69 Skyworks devices.The Si21622C offers an on-chip blind scanning algorithm for the DVB-C, as well as blind lock function. The Si21622C embeds two independent programmable transport stream interfaces which provide a flexible range of output modes, including a cross-bar functionality, and are fully compatible with all MPEG decoders or conditional access modules to support any customer application.Features-Pin-to-pin compatible with all dual demodulator family: Si216x2 and Si218x2-API compatible with all single and all dual demodulators-DVB-T2 and T2-Lite (ETSI EN 302 755-V1.4.1)-Bandwidth: 1.7, 5, 6, 7 or 8 MHz-NorDig Unified 2.5 and D-Book 8 compliant-DVB-C2 (ETSI EN 302 769)-16-QAM to 4096-QAM OFDM demodulation-DVB-T (ETSI EN 300 744)-NorDig Unified 2.5, D-Book 8 compliant-DVB-C (ETSI EN 300 429) / ITU-T J.83 Annex A/B/C-1 to 7.2 MSymbol/s, C-Book compliant-I2C serial bus interfaces (master and host)-Upgradeable with firmware patch download via fast SPI or I2C (broadcast mode supported)-Dual independent differential IF input for T/C tuners-GPIOs and multi-purpose ports (two per demodulator)-Separate flexible TS interfaces with serial or parallel outputs and cross-bar feature-Fast lock times for all standards-Only two power supplies: 1.2 and 3.3V-8x8mm, QFN-68 pin package, Pb-free/RoHS compliant Applications-Multi-receiver iDTV: on-board or in a NIM-Advanced multimedia PVR STBs-PC-TV accessoriesSelected Electrical Specifications (T A =–10 to 70°C).ParameterTest Condition Min Typ Max Unit GeneralInput clock reference 4—30MHz Supported XTAL frequency 16—30MHz T otal power consumption for each demodulatorDVB-T21—356—mW DVB-T 2—182—mW DVB-C23—327—mW DVB-C 4—142—mW Thermal resistance ( JA ) 4 layer PCB—42—°C/W Power Supplies V DD _VCORE 1.14 1.20 1.30V V DD _VANA 3.00 3.30 3.60V V DD _VIO3.003.303.60VNotes:1.

The process and choice of materials result in low series resistance with a narrow spread of capacitance values for close impedance control.A variety of forward voltages are available ranging from low values for low, or starved, local oscillator drive levels to high values for high drive, low distortion mixer applications. These Schottky barrier mixer diodes are available in a wide range of packages.Capacitance ranges and series resistances are comparable with the packaged devices that are available up to, and including, the Ka-band.Schottky barrier diodes are categorized by universal mixerapplications in six frequency ranges: S, C, X, Ku, K, and Ka bands as noted in Table 1. They may also be used as modulators and high-speed switches.The absolute maximum ratings of the DME, DMF, and DMJ series of Schottky mixer diodes are provided in Table 2.

关于中国电信2.1G NR天馈安装方式的研究发布时间：2021-11-29T03:11:57.350Z 来源：《现代电信科技》2021年第14期作者：倪竹青[导读] 本文根据中国电信集采的5G设备、天线形态，结合现有网络的天馈频段、型号和塔桅租赁情况，对2.1G NR网络天馈建设部分进行分析，制定最优的天馈建设方案，达到节省建设投资和维护成本的目标。

（中通服咨询设计研究院有限公司江苏南京 210000）摘要：本文根据中国电信集采的5G设备、天线形态，结合现有网络的天馈频段、型号和塔桅租赁情况，对2.1G NR网络天馈建设部分进行分析，制定最优的天馈建设方案，达到节省建设投资和维护成本的目标。

关键词：5G；2.1G NR；天馈；租金引言2021年是实施“十四五”规划、开启全面建设社会主义现代化国家新征程的第一年。

5G建设投资较大，在现阶段无足够的业务实现运营商的利润需求。

在制定方案时应综合考虑投资成本和维护成本，在满足5G天馈安装空间及覆盖的要求下，应重点关注无线网络简化、TCO 最优原则，需对5G网络天馈整合方案精细分析，优化资源调整，边试点边实施，有效的推进整合工作顺利进行，力争达到“节省投资、降低网络成本、提升网络竞争力、合作共赢”的目标。

1 2.1G NR设备、天线形态 1.1 设备形态中国电信集采的2.1G NR设备为BBU+RRU形态，射频拉远单元与天馈系统独立分开。

BBU的形态与4G相同，RRU为4通道的4T4R （4*80W）设备。

相关参数如下：（1）BBU物理形态及参数2.2 连云港联通天馈现状联通现网有GSM900、DCS1800、900M、WCDMA、L1.8G、L2.1G六套系统，其中GSM900和900M全部共天线。

天馈组网相对复杂，除原联通自有产权的基站外，现网很少有独立天馈，基本以双频天线为主。

3、方位角：在进行5G基站天线方向设置时，天线主瓣方向可考虑与4G天线同方向，且100米范围内无明显阻挡。
