Digital MUDS Broadband Transmitter
Outline
JXUT-X series transmitter adopts directly amplifying working model. Receiving modulated intermediate carrier, then amplifying it with high gain and high linearity, connecting to 50/N model connector jack of this panel; when it is used, it is connected to transmitter’s antenna with RF cable. The capability of transmitter continuous work is dependent on all components of transmitter. When this system is working, it must be supplied by electric power and needs lightningproof equipment.
Features:
Automatic close loop electrical level controlling design guarantees stable output power of the transmitter.a linearity design of low power disssipation promotes the power of transmitters and reduces the non-linearity distortion products.power supply unity owns automatic protection design for overpressure, overflow, overtemperature, open circuit and short circuit, enhances stable operation of transmitters.digital/ analogue compatibility. It adapts to various modulation modes (users need to decide which modulation mode you need.)outdoor self heat cooling (<50W) + air-cooling design (≥50W). power faliure protection when over temperature.Outdoor design, easy to install.Specifications:
