Since our founding back in 2009, Epiq has strived to provide our customers with unique and differentiated RF and SDR capability in small size, weight, and power (SWaP) form factors. In the early days, this was represented in our M.2 and MiniPCIe products that provided full SDR sub-systems in a stick of gum size card that weighed less than 10 grams and consumed less than 3W. Over the years customers have continued to ask Epiq for more – more bandwidth, more frequency coverage, more channels, and more processing – while still keeping SWaP as small as possible.
processing, while still working within the SWaP constraints of a battery powered, portable system. Those requirements are at odds with each other, and demand innovation to provide an elegant solution.
Epiq’s recent product releases like the Matchstiq X40 respond to these emerging use cases and requirements by expanding frequency coverage, bandwidth, and integrating Nvidia GPU/CPU processing in the SDR platform. Epiq’s engineers continue to innovate and advance our SDR platform footprint, and today we are pleased to announce the two newest products to the family: Matchstiq Z4 and V40.
The Z4 is optimized for battery powered and on-the-move applications. Consuming less than 20W and with length and width similar to a large smartphone, the Z4 can be deployed in handheld, manpack, or UxS scenarios. In that small form factor, the Z4 packs a very capable RF punch, with four RF channels that can be assigned to receive or transmit functionality, complete RF front end including sub-octave preselection, a large AMD Ultrascale+ MPSoC, and auxiliary functionality like a GPS disciplined oscillator and IMU. In addition, the Z4 introduces two new capabilities for an Epiq product, 1) an embedded system controller that can take the Z4 in and out of low power modes, extending
system battery life, and 2) two internal M.2 2280 sites that provide a modular platform capability to the product. Initially populated with TB SSDs for IQ storage, Epiq plans to introduce new modules to the family, including extensions to HF and 18GHz frequency coverage.
The V40 is optimized for wideband, high RF capacity applications, and represents the adoption of three new important technologies into Epiq’s product family: 1) direct RF sampling as a radio architecture using the Analog Devices AD9084 Apollo MxFE, 2) AMD’s Versal Adaptive SoC signal processing, and 3) 100GbE network interfacing. The direct sampling architecture of the V40 gives the SDR its high instantaneous bandwidth of 2GHz on both receive and transmit, as well as its high level of performance and low latency characteristics. The Versal is AMD’s latest generation of advanced SoC devices, and provide more compute-per-watt than any prior generation of system-on-chip, allowing for the V40 to process the wide bandwidth created by the direct sampling front end. Finally the 100GbE interfaces allows for networked SDR and RF sensor implementations that can transfer the wide digitized bandwidth between remote sensors and backend processing systems. The V40 integrates all of this advanced technology in a low SWaP form factor, measuring fewer than 50 cubic inches in size and consuming 40W in a typical use case.
The RF landscape and wireless requirements are constantly evolving – more rapidly now than ever before. Epiq continues to invest heavily in new technologies to provide our customers with SDR platforms that are optimized for critical use cases and deployment concerns and is excited take both the Z4 and V40 out from behind the curtain at the 2025 AOC symposium in Washington DC.
