The feature of this combline filter is its ability to pass the wanted frequencies and to reject all unwanted frequencies, thus providing protection from neary transmitters.
Its higher protection against receiver desensitization makes it suitable for use at congested urban sites.
This model filter is engineered to provide greater than 30dB isolation @ FH +0.25% and greater than 20dB isolation @ FL -0.25%.
Passband bandwidth is 2.8 MHz with other configurations available to order. | | | |
This model consists of 5 resonators enclosed in a compact aluminium housing optimised to ensure a compromise between passband, selectivity and physical dimensions.
The cavities are tuned to resonace with a capacitive tuning element this allowing a maximum resonator depth of 80mm.
This allows a highly selective filter to be mounted in the minimum of space.
The input and output connectors are N Female, and the unit is finished in grey enamel paint.
The robust mechanical construction ensures excellent mechanical stability and trouble free operation. | | | |
| All duplexers are factory tuned to customer specified frequncies, but may be field retuned. | | |
