Digital Signal Receivers

RF Spectrum Receivers

PPM Systems offers the R4000 range of IZT Spectrum Receivers, which are off-the-shelf units, and MAC Spectrum Receivers for board-level integration into equipment. MAC receivers include the MONITOR range MON4000 and CatchAll-M2.

'Plug and play' units: R4000 range

The IZT R4000 delivers an immensely powerful digitiser, wideband receiver and signal collection system for COMINT and ELINT systems, wideband satellite surveillance and continuous broadband radio signal recording. It achieves an instantaneous bandwidth of 120 MHz and covers an impressive frequency range of up to 18 GHz.

The all-digital receiver boasts a very high dynamic range also in high-bandwidth applications, and has the ability to store and analyse the huge amounts of data that come with this increased instantaneous bandwidth in a typical operating environment. It features a backend digital storage system and dedicated parallel signal analysis engines to support multiple users. Further, the R4000 includes highly-selective configurable signal pre-selectors to avoid signal overload problems, high-quality RF frontends, and broadband digitisers.

Board-Level/OEM: MON4000

MON4000 – Dual-channel, Multi-band Down-converter

MAC MON4000 spectrum receiverThe MON4000 card is the latest software defined radio platform in MAC Ltd’s MONITOR family. Primarily designed for off-air test applications in cellular radio bands the MON4000 boasts two channels of RF-to-bits conversion for up to six distinct bands in the frequency range 400 MHz to 4000 MHz. Each receiver uses an IF sampling architecture to guarantee excellent dynamic range as needed for use in a multi-channel environment. Local processing is performed by a Xilinx Zynq 7020 FPGA and two gigabit Ethernet channels carry baseband samples to the host. With external support the MON4000 can also be used in phase-coherent applications.

Applications of the MON4000 card include cellular band test receivers, direction finding, beamforming systems, MIMO reception, multi-channel wideband receivers and unattended monitoring systems.

Board-Level/OEM: CatchAll-M2

CatchAll-M2 Dual-channel multi-band receiver

The CatchAll-M2 is a dual-receiver, multi-band radio frequency front-end device (FED) designed for operation in the commonly used mobile radio frequency bands between 160 MHz and 4 GHz.

It is based on MAC Ltd’s MON4000 software-defined receiver card and – in addition to the six frequency bands supported by the MON4000 – the CatchAll-M2 adds support for 160-180 MHz VHF and 300-480 MHz UHF bands. The six bands provided by the MON4000 can be chosen at time of manufacture from a wide range of available bands. Please see the MON4000 datasheet for a list of available options.
