Balanced UHF TV Combiners
Rev : 01 | Rev date : 02 Jun 2017
This series of constant impedance UHF combiner modules is designed for multichannel digital and/or analog TV combining applications. These modules are designed in sizes including 50E, 100E, 150E and 200E. They are available with 3 pole, 5 pole, 6 pole cross-coupled, 7 pole and 8 pole filters making them suitable for all low to medium power applications.
These balanced UHF TV combiners are ideal when optimum performance specifications are required. They are extremely compact, as well as being temperature stable and suitable for a wide range of applications.
Each balanced combiner module consists of two 3dB couplers, separated by two coaxial or bandpass filters. The filters are designed according to channel spacing and power rating.
The narrowband input corresponds to the bandpass resonant frequency, whereas the wideband input can be any other channels in the applicable TV band. Modules can be connected together to provide a multi-channel combiner with eight or more channels possible. Bandpass coaxial filters are designed as 3, 5, 6, 7 or 8 pole to suit the following channel separations:

Bandpass coaxial filters are designed as 3, 5, 6, 7 or 8 pole to suit the following channel separations:
- 3 pole: 3 channels or greater. For example channels 31 and 34
- 5 pole: 2 channels or greater. For example channels 31 and 33
- 6, 7 or 8 pole: adjacent channels. For example channels 31 and 32
