United Kingdom – October 27, 2026 -- ST Engineering iDirect's 450SDM software-defined modem is 30% smaller than its predecessor, and Paradigm is integrating it into its PIM-based tactical terminals for government and defense users, according to Paradigm founder Ulf Sandberg.

PIM architecture links iDirect modems to lightweight terminals

Paradigm's Paradigm Interface Module (PIM) integrates the iDirect 950mp and the new 450SDM into a single platform, yielding the PIM950 and PIM450 configurations. Users can switch between software-defined profiles at the touch of a button. Sandberg said the 450SDM's compact form factor suits lightweight systems such as the backpack-ready RAGNO terminal, and that it supports multi-orbit and multi-waveform operation. The single-case HORNET terminal uses the same approach.
