SDRPlay RSPduo 1KHz to 2GHz SDR Receiver

The new SDRPlay RSPduo is a 14-bit SDR dual receiver that covers from 1kHz to 2GHz (without hole), with dual-tuner (simultaneous reception on 2 different antennas).


SKU 0027 Category Tag


The SDRplay RSPduo is a dual-tuner wideband full-featured 14-bit SDR that covers the entire RF spectrum from 1kHz to 2GHz giving 10MHz of spectrum visibility. Combined with the power of readily available SDR receiver software (including ‘SDRuno’ supplied by SDRplay) you can simultaneously monitor two completely separate 2MHz bands of spectrum anywhere between 1kHz and 2GHz.

The RSPduo provides three software selectable antenna inputs, and clocking features ideally suited to industrial, scientific and educational applications. All it needs is a PC and an antenna to provide excellent communications receiver functionality.

A documented API allows developers to create new demodulators or applications around the platform.

Key Benefits

Simultaneously receive on two totally independent 2MHz spectrum windows anywhere between 1kHz and 2GHz

Simultaneous processing from 2 antennas enables direction-finding, diversity and noise reduction applications

  •  Ideal for cross band full-duplex reception, e.g. HF + VHF or VHF + UHF
  •  Simultaneous Dump1090 and VHF ATC reception
  •  Simultaneous monitoring and recording of 2 ISM bands
  •  Covers all frequencies from 1kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2GHz, with no gaps
  •  Receive, monitor and record up to 10MHz of spectrum at a time (single tuner mode)
  •  External clock input and output for synchronization purposes, or connection to GPS reference clock
  •  Excellent dynamic range for challenging reception conditions
  •  Works with popular EXTIO-based SDR software (available mid-2018)
  •  Software upgradeable for future standards Strong and growing software support network
  •  API provided to allow demodulator or application development
  •  Calibrated S meter/ RF power and SNR measurement with SDRuno (including data logging to .CSV file capability)
  •  Ideal for portable monitoring of ISM/ IoT/ Telemetry bands <2GHz
  • World-class technical support via

Key Features

  • Dual tuner provides independent coverage from 1kHz to 2GHz using 2 antenna ports simultaneously
  • 14-bit ADC silicon technology (not another 8-bit dongle!)
  •  Up to 10MHz visible bandwidth (single tuner mode) or 2 slices of 2MHz spectrum (dual tuner mode)
  •  3 software-selectable antenna ports ( 2 x 50Ω and 1 x 1kΩ high impedance balanced/unbalanced input)
  •  High impedance antenna port (1kHz to 30MHz) with selectable MW notch filter and choice of 2 pre-selection filters
  •  Software selectable AM/FM and DAB broadcast band notch filters for the 2 SMA antenna (1kHz to 2GHz) antenna ports
  •  External clock input and output enables easy synchronization to multiple RSPs or external reference clock
  •  Powers over the USB cable with a simple type B socket
  •  11 high-selectivity, built-in front-end preselection filters on both the 2 SMA antenna ports
  •  Software selectable multi-level Low Noise Preamplifier
  •  Bias -T power supply for powering antenna-mounted LNA
  •  Enclosed in a rugged black painted steel case.
  •  SDRuno—World Class SDR software for Windows
  •  Documented API for new apps development
