Resistive power divider 1→2, broadband, module

Product detailed description

The 1→2 resistive power splitter divides an RF signal from one input into two outputs over an extremely wide band from DC to 5 GHz. The splitter consists of a trio of resistors connected in a star configuration, so unlike microstrip splitters, it has no lower frequency limit and operates uniformly from low frequencies up to the 5 GHz band. All ports have an impedance of 50 Ω and SMA (female) connectors; the splitter is passive and also functions as a combiner in the reverse direction. It is suitable for laboratory measurements, splitting a signal from a generator into two instruments, monitoring a signal with an analyser or oscilloscope, and connecting two SDR receivers to a single antenna.

Specifications:

• Type: passive resistive power splitter / combiner 1→2
• Frequency range: DC – 5 GHz
• Output insertion loss: 6 dB
• Impedance: 50 Ω
• Max. power: 0.5 W (27 dBm)
• Connectors: 3× SMA female (1 input, 2 outputs)
• Power supply: not required (passive component)
• Dimensions: approx. 33 × 33 mm (excluding connectors)
• Mounting: 4 mounting holes
• Typical applications:
  • splitting a signal from a generator into two devices
  • one antenna for two SDR receivers
  • signal monitoring using an analyser or oscilloscope during operation
  • combining two signals (e.g. for two-tone measurement)
• For low attenuation and higher output isolation in the 0.5–6 GHz band, the following is suitable:
  • SMA Power Divider 1→2, 0.5–6 GHz, microstrip

Important wiring notice:

• The resistive splitter has an attenuation of 6 dB at each output (3 dB more than a microstrip splitter) and the isolation between outputs is only approx. 6 dB – the signal from one output leaks into the other. For weak signals, place a low-noise amplifier (LNA) before the splitter.
• The splitter also passes DC voltage – if you power an active antenna or LNA via coax on one port, the voltage will reach the other ports as well.
• Do not exceed a power of 0.5 W (27 dBm); the power is converted to heat in the resistors.
