SMA Power Divider 1→2, 0.5–6 GHz, microstrip

Product detailed description

The passive microstrip 1→2 power splitter for the 0.5 to 6 GHz band evenly splits an RF signal from one input into two outputs with SMA connectors. It is ideal for connecting a single antenna to two receivers or SDRs, for distributing GNSS, ADS-B, LoRa or Wi-Fi 2.4/5.8 GHz signals, or for measurements where you need to monitor the signal with an analyser simultaneously. A low VSWR (< 1.2) ensures good matching to a 50Ω system, the insertion loss is at most 0.6 dB above the theoretical 3 dB splitting loss, and the isolation between outputs of at least 20 dB prevents mutual interference between the connected receivers. The circuit is enclosed in an aluminium housing, requires no power supply, and also functions as a combiner of two signals into one when used in reverse.

• Typical applications:
  • single antenna for two receivers / SDR (ADS-B, GNSS, LoRa, Meshtastic)
  • splitting or combining 2.4 and 5.8 GHz Wi-Fi signals
  • measurement and laboratory work with RF signals

Important wiring notice:

• The signal is split between the outputs, so it is approximately 3–3.6 dB weaker at each output than at the input. For long cables or weak signals, place a low-noise amplifier (LNA) before the splitter.
• If one output is not in use, terminate it with a 50 Ω load to improve matching and isolation between ports.
• The splitter is intended for reception and low-level signals; do not connect it to the output of a power transmitter.
