Description


Telewave The Telewave Bandpass Notch Cavity Filter is a dual 4" diameter, ¼-wavelength notch cavity with an adjustable coupling loop. Notch cavities are typically used together with Pass or Pass/Reject cavities to eliminate a particular frequency. Notch cavities have a very low loss outside the notch band.

The cavity covers 763-869 MHz. The cavity features a positive locking mechanism that allows for quick field re-tuning if frequency changes become necessary. The cavity features a calibrated adjustable coupling, which can be easily changed to improve selectivity. This allows cavity response to be optimized for any operating environment. At densely populated sites the filter provides greater selectivity with minimum insertion loss. Multiple cavities can also provide a wider notch when required. Mounting rails are provided for all multiple cavity filters.

Excellent frequency stability is achieved by the use of a specially machined compensator and Invar rod. The pass and reject frequencies are temperature stable from -30°C to +70°C. Telewave Ground Loop technology places the center conductor of each coupling loop at DC ground potential for lightning protection and noise reduction. Heavy-duty materials are used throughout each cavity to ensure high performance and long life. Cavity top and bottom plates are machined from ¼-inch aluminum and are heliarc welded to the cavity body for improved conductivity and strength. This allows Telewave cavities to handle up to 350 watts. Similar metals and alodined aluminum help prevent galvanic corrosion. Silver plated tuners and beryllium copper finger stock provide non-corrosive low loss contact and ensure reliable, long-term performance.
