SpectraScopeRT
In today’s RF landscape, signal standards are advancing rapidly requiring higher frequencies and broader bandwidths for mission-critical applications such as 5G wireless, satellite
GaGe offers a selection of RF Downconverter models that can cover narrowband frequencies starting at 9 kHz to wideband frequencies up to 40 GHz, with instantaneous bandwidths (IBW) that range from 10 MHz up to 500 MHz. The outputs of the RF Downconverters are connected to the channel inputs of high-speed PCIe Digitizers with suitable input bandwidth and A/D sampling rates for the targeted application.
All RF Downconverter models are supported with SpectraScopeRT, a Windows based spectrum analyzer application that requires no programming and allows for integrated operational control of both the RF Downconverter and the Digitizer for signal capture, analysis, and real-time signal monitoring and signal recordings.
A-27 Series: Compact Wideband Frequency Down Converter
The A-27-Series wideband downconverter models are purpose-built for modern signal standards, offering RF input ranges from 9 kHz to 27 GHz and bandwidths up to 160 MHz. With selectable Zero-IF and Super-Heterodyne modes, this system accommodates flexible IF outputs optimized for different digitization workflows.
Weighing just 2.7 kg and consuming under 25W, this ultra-portable frequency down converter supports both narrowband and wideband testing requirements across 5G, EW, SIGINT, and satellite communications.
Key highlights include:
- Dual model options: 9 kHz–8 GHz or 9 kHz–27 GHz
- Software-selectable IF bandwidths: 10 MHz to 160 MHz
- Pre-select filtering with up to 21 filter banks for out-of-band rejection
- Pre-amplifier on the 27 GHz model for improved sensitivity
- Multi-channel synchronization with 10 MHz reference input/output
- Seamless integration with GaGe high-speed digitizers for real-time streaming
With its support for both IQ and single-channel IF outputs, the A-27-Series serves as a versatile RF up down converter, capable of supporting broad-spectrum applications across aerospace, research labs, and high-frequency testbeds.
A-40 Series: Ultra-Wideband mmWave RF Downconverter
Engineered for the most demanding RF test environments, the A-40-Series is a next-generation wideband downconverter that supports frequencies from 24 GHz to 40 GHz. With a fixed 500 MHz IF output bandwidth centered at 1.536 GHz, it is ideally suited for mmWave 5G FR2 channel testing, EW, and broadband spectrum surveillance.
The A-40’s compact form factor (1.7 kg) and energy-efficient 20W power draw make it an excellent choice for field or rackmount deployment.
Technical features include:
- Wide 24 GHz–40 GHz input range
- 500 MHz instantaneous bandwidth
- 100 kHz tuning resolution
- 8-channel pre-select filter bank and internal pre-amplifier
- Real-time streaming support via high-speed digitizers (e.g., EON Express 6 GS/s)
- Seamless compatibility with SpectraScopeRT and SpectraViewRT for live monitoring and playback
This high-performance RF downconverter supports continuous data capture for up to 11 hours using PCIe streaming and scalable storage systems up to 192 TB. Additionally, it can be daisy-chained with the A-27-Series for full-spectrum coverage of both sub-6 GHz and mmWave signals—making it an adaptable RF up down converter solution for comprehensive testing.
