Even Splitters

Even Non-Isolated Splitters

For broadband Combining / Dividing applications, where port-to-port isolation is not required, Werlatone provides Bi-Directional designs. Utilized to evenly split a single run of 50 Ω coaxial cable, hosting multiple frequency bands, into 2,3,4, or more corridors, tunnels shafts, or rooms.

Non-Isolated Splitters are bi-directional and unlike Isolated Splitters, all ports can communicate with one another (See Schematic A).

Even ISOLATED Splitters

For broadband Combining / Dividing applications where port-to-port isolation is required, Werlatone provides 2-Way, 4-Way, and N-Way Combiners / Splitters. Where specified, we design our Combiners to tolerate full input failures on adjacent port(s). This insures that remaining transmitter(s) may continue to operate until the amplifier system can be properly shut down for maintenance (See Schematics B & C).

Non-Isolated UNEVEN Splitters (Taps)

Utilized to un-evenly split a single run of 50 Ω coaxial cable, hosting multiple frequency bands, so that a shorter corridor, tunnel, shaft, or hallway is provided a lesser proportion of the power on the main coaxial run than that required by a longer run.

Non-Isolated Uneven Splitters are bi-directional and unlike Directional Couplers, all ports can communicate with one another (See Schematic D).

Uni-Directional Couplers

A 3-Port Uni-Directional Coupler consists of a main line and a coupled line. One end of the coupled line is internally terminated, while the other end serves as a coupled port.

Ideal for sampling and monitoring power in one direction at a given time. It is necessary to physically reverse the orientation of the unit to change from a forward to a reverse power measurement (See Schematic E).

Dual Directional Couplers

A 4-Port Dual Directional Coupler employs two, 3-Port Uni-Directional Couplers internally connected, in tandem, providing measurement of both forward and reverse power.

Ideal for simultaneously monitoring a system’s forward and reverse power and for reflectometer measurements. Unlike the Bi-Directional Coupler, the directivity of the Dual Directional Coupler is unaffected by the loads on the coupled ports (See Schematic F).

Multi-Channel Hybrid Combiners

  • VHF
  • UHF
  • 700 MHz
  • 800 MHz

Werlatone’s Mismatch Tolerant® Hybrid Combiners are cost effective, compact, rack mounted solutions. Hybrid Combiners eliminate on-site tuning (or retuning) during installation (or maintenance) as there is no performance drift due to temperature, vibration, or shock.

Designed to combine multiple high power transmitters within a service band (VHF, UHF, 700 MHz, and 800 MHz). Each combiner provides between 45 and 75 dB port-to-port isolation depending on the isolator utilized, and is available with optional Low Pass Filters and Directional Couplers (See Schematic G).

Custom Approach:

  • Combine 2-12 Channels within a given service band.
  • Connector choices and locations to customer specification.
  • Optional Non-Reflective Low Pass Filters which terminate all out-of-band harmonics.
  • Port-to-port isolation at 45 dB or 75 dB, depending on application.
  • Optional low loss Uni or Dual Directional Couplers (6-40 dB Coupling) for uneven splits prior to combiner output or for internal power measurements.
  • Cooling Fans: 110/220 VAC or 24V DC.
  • Designed for MIL-STD-810 Vibration and Shock.
  • Designed for -55°C to +70°C ambient temperature.

Absorptive Filters

  • Low Pass
  • High Pass
  • Band Pass
  • Notch
  • Cross Band

Out-of-band signals are not reflected back to the source!

  • The Out-of-Band Signals are internally terminated, preventing them from generating undesirable intermodulation products.
  • In-Band Signals are transmitted through the filter.

 

Benefits

  • Our Mismatch Tolerant® design greatly reduces the dependency of the system on the length of interconnecting cable between two non-perfect components (eg. Between Power Amplifier and Antenna).
  • Our electrical specifications are less susceptible to temperature change.
  • We eliminate instability of power amplifiers at out-of-band frequencies.
  • We eliminate excessive In-Band ripples due to out-of-band reflected energies.
  • We eliminate the false trigger of power-detector circuitry due to reflected harmonics.
  • We eliminate potential damage to power amplifiers due to reflection of high power out-of-band energies.
