SDR-3104
‍Software-Defined Radio

3U SpaceVPX SDR with extended low-frequency receive coverage

Overview

SDR-3104 is a software-defined radio with 4 transmit and 4 receive channels in a ruggedized 3U SpaceVPX form factor, designed for multi-channel RF digitization and signal processing within spacecraft payload architectures.

SDR-3104 maintains the same core architecture as SDR-2104 while direct-sampling from UHF through Ka-band. This simplifies system design and enables greater channel density and processing performance.
