Tilted hybrid taps are the latest breed of outdoor passives using an innovative directional coupler design. Traditional outdoor passives use ferrite loaded transmission line couplers. Although, with ever increasing bandwidth demands, these ferrite couplers are becoming the weakest link in a cascaded or tree-and-branch network.
Frequencies up to 1220 MHz and higher are now being used and as a result the insertion loss budget of the total link becomes an issue. There is also, of course, increased cable loss at higher frequencies, although there is little that can be done to avoid this. The most important factor is the insertion loss of the many cascaded taps.
The advantages of tilted hybrid technology is that it uses an innovative hybrid architecture with a traditional ferrite directional coupler to carry lower frequencies and a microstrip directional coupler for carrying the higher frequencies.
The combination of low tap loss produced at low frequencies of the ferrite coupler and extremely low insertion loss at high frequencies of the microstrip directional coupler, provides the best of both worlds.
The innovative Technetix architecture means there is no specified cross-over frequency band (typical for conditioning taps) between the ferrite coupler and the microstrip coupler.
Maximum flexibility is achieved as the taps have no specified upstream and downstream range, providing a limitless choice in frequency range.
Additionally, this technology offers automatic return path balancing (without the need for conditioning diplexers) and cable characteristic compensation. Current Tilted Hybrid Taps are specified up to 1400 MHz and offer a future proof solution.
