DCA18G160 RF Receiver & Downconverter, 18 GHz
The DCA18G160 is a RF Riciever and Downconverter featuring breakthrough frequency and bandwidth coverage for the size and cost, covering frequency ranges from 9 kHz to 18 GHz.
The DCA18G160 downconverters has a bandwidths of 100 MHz direct conversion (centered at 0 Hz IF) I and Q analog outputs. These wideband version can be software configured for super-heterodyne mode with a bandwidth of either 40 MHz or 10 MHz on a single IF output centered at 35 MHz IF.
The DCA18G160 is engineered for analyzing wideband digital communications - cell phone standards 3G/4G/LTE, WiFi, or general Vector Signal Analysis (VSA) applications involving broadband signals.
The DCA18G160 RF front end is a unique architecture, consisting of both super-heterodyne and direct conversion technologies that are software selectable. The front-end processing blocks utilize 9 preselect filters to mitigate input-related spurs and image responses.
The DCA18G160 model combined with GaGe high-speed digitizers allow for complete real-time signal recording and analysis systems covering frequencies up to 18 GHz RF Signal spectrum. These solutions greatly extend the digitizer's frequency range allowing those developing applications in R&D, Manufacturing Test, and Field Service a high performance lower cost platform for complex wideband RF and microwave signal analysis.
The DCA18G160 bandwidth modes of 160 MHz, 80 MHz, and 10 MHz ideally suited for use with GaGe 16-bit resolution Razor Express 16XX PCIe Digitizer at up to 200 MS/s or RazorMax at up to 500 MS/s or 1 GS/s for real-time gap free signal recording at 100 MHz bandwidth.
10 MHz reference inputs and outputs on both the GaGe digitizers and downconverter units provide a single frequency reference for synchronized operation for multiple systems.
The large onboard FIFO memory of the GaGe digitizers allow for real-time streaming of I and Q baseband signals at up to 1.6 GB/s (Razor Express) or 5 GB/s (RazorMax Express or EON Express) over PCI Express to PC memory for post processing, display, and storage.
The digitizers and downconverters have full control and data acquisition support via Mathworks MATLAB, with example programs furnished to facilitate rapid signal processing and modulation analysis program development. Additional software SDK and example programs are available for C/C# and LabVIEW.
For manual control, testing and setup of the Ethernet connected downconverters, programs are provided for network discovery, setting carrier frequency, RF / IF gain, filters, etc.
SpectraScopeRT is a Windows based spectrum analyzer application software that requires no programming and allows for integrated operational control of both the downconverter receiver and the digitizer for signal capture, analysis, and recordings. SpectraViewRT is used to conduct playback of previous signal recordings to the display monitor for analysis.</div
