Sidekiq™ Multi-Channel RF Transceiver – X2 and X4

The programmable Sidekiq X2 and X4 from Epiq Solutions are multi-channel RF transceiver cards that introduce a new level of RF integration and capability, reducing product development times and improving wideband range, versatility, and performance. Sidekiq creates a flexible, high-capacity RF transceiver solution that is designed for pairing (as shown in photo) with a high-performance WILDSTAR FPGA Baseboard.

Sidekiq X2 and X4 cards provide up to four phase-coherent RF transceivers covering 1 MHz to 6 GHz, all within a VITA 57.1 FPGA Mezzanine Card (FMC) form factor. RF performance is enhanced with 16-bit A/D converters and 14-bit D/A converters.

Sidekiq is readily integrated into COTS 3U or 6U VPX carrier cards. Both conduction- and convection-cooled options are supported.

The Sidekiq Platform Development Kit (PDK) provides customers with access to both a software API for interfacing to the card, as well as the source code for the FPGA reference design.
