Telewave TPRD-4744 Duplexor de 4 cavidades, ajuste en fábrica, 3MHz, 400-512MHz Conector N-H (A pedido por importación 10-12 semanas) Precio con iva incluido

DUPLEXOR UHF MARCA TELEWAVE RANGO 470-512 MHZ

Duplexor de Paso y Rechazo de banda, permite el funcionamiento simultáneo de un transmisor y un receptor con una sola antena, son una opción para sitios de repetición donde se disponga de poco espacio físico y se requiera de gran aislación. Poseen dos cavidades de Paso Rechazo en la sección transmisión y dos en la de recepción, logrando así un mayor rechazo al ruido y a la radiación de espuria en el transmisor, proporcionando además una excelente protección al receptor. Su construcción con sintonizadores plateados, contactos de cobre y berilio, varillas de INVAR (Hierro & Niquel + Carbono) aseguran una gran estabilidad, una gran calidad y muchos años de funcionamiento. Los precios incluyen los cables de interconexión y rieles de montaje. Todos los duplexores son entregados sintonizados y ajustados a las frecuencias de trabajos, las cuales debe ser proporcionadas por el cliente.

The Telewave.io TPRD-4544/4744 Base Station Duplexers provide high performance with an innovative design. By using two TPRC-4504 or 4704 Pass /Reject cavities in the transmitter and receiver path, these duplexers provide maximum TX to RX protection in the most severe RF environments.

The design of these duplexers provides a bandpass characteristic with minimum insertion loss, while also providing maximum TX to RX protection. Adjustable coupling optimizes the required attenuation for ideal RX performance. All cavity inputs are electrically shorted to ground for maximum static and noise protection.

RG-214 Mil-Spec cable is used for all interconnections to ensure long life, and lowest insertion loss with maximum power handling capability. Heavy-duty materials are used in construction of these duplexers, including silver-plated tuners and beryllium copper finger stock contactors, assuring high “Q” performance with no problems due to dissimilar metals. Tuning is simple and remains stable from -30°C to +70°C, thanks to the threaded Invar rod.

All duplexers are tuned and tested with customer-specified frequencies prior to shipping. No further adjustments should be required.

The positive locking mechanism allows for simple field tuning if frequency changes are required.

TPRD-4544/4744 duplexers mount on a 19” standard rack, with panel height of 5.25”. Power handling is 250 watts. Receiver desense protection is at least 90 dB, and TX sideband suppression is at least 75 dB.

With TX to RX spacing of 3 MHz or more, this duplexer can also combine two transmitters into one antenna, or feed two receivers. For spacing less than 3 MHz, please contact Telewave.io for assistance.
