TELE发射器NDB系列JTM-30C介绍
NDB 发射器类型 JTM-30C 是一种无方向性无线电信标 (NDB) 发射器，设计用于石油钻井平台和船舶上的车载使用以及其他应用。
JTM-30C 有两种不同的射频功率输出版本（100W PEP 或 200W PEP），作为具有一个完整发射链的单 NDB 发射器配置，或作为双 NDB（或冗余）发射器，具有两个完整的发射链，具有故障检测/报告和自动切换功能，以及通用天线调谐。
发射机调谐以匹配天线阻抗是一个手动过程。自动调谐单元作为选配提供。该设备基于NDB发射机的全新概念，采用数字激励器。发射机具有以下主要特点：
JTM-30C 是一款一体化设备，包含天线调谐电路、激励器（用于产生输出信号）、射频功率放大器以及控制和监控电路。交流电源和直流电源也可安装在 IP66 防风雨加固型发射机机柜内。
柜内装有加热元件，以降低低温下的湿度。
NDB Transmitter Type JTM-30C is a Non-Directional Radio Beacon (NDB) Transmitter designed for onboard use on oilrigs and ships, as well as for other applications.
The JTM-30C is available in two different RF Power output versions (100W PEP or 200W PEP) as Single NDB Transmitter configuration with one complete transmit chain, or as
Dual NDB (or Redundant) Transmitter with two complete transmit chains with fault detection/reporting and automatic changeover, common Antenna Tune.
Transmitter tuning to match the antenna impedance is a manual procedure. Auto Tune Unit is offered as an option. The equipment is built upon a totally new concept for NDB transmitters utilizing digital Exciters. The transmitters have the following main features
JTM-30C is indeed an ALL-IN-ONE unit consisting Antenna Tuning Circuits, Exciter(s) (generating the output signal), RF Power Amplifier(s) and Control & Monitoring circuits. The AC Mains & DC Power Supply may also be installed inside the IP66 weatherproofed and ruggedized Transmitter cabinet.
A heater element is installed inside the cabinet to reduce humidity at low temperature.
