Spectrum Monitoring

Espy’s primary mission focus is on discovery, visualization and exploitation of the RF spectrum. Our integrated RF wideband recording capability gives teamSENTINEL sensors cast-iron coverage of the entire HF and large parts of the V/UHF frequency range0F, with workflows and GUIs that allow for comprehensive real-time and post-facto analysis of that environment down to the hertz, if required. Even with easy access to these very large RF datasets, the challenge remains on how best to exploit the overwhelming volume and diversity of signal information processed and stored on these sensors.

Spectrum Purification

Our RF Microwave product portfolio comprises many single- and multi-function integrated microwave filter assemblies and subsystems. MPG manufactures an extensive range of both surface mount and connectorized products including ceramic, lumped element, cavity, waveguide, Suspended Substrate, thin film, and tunable filters

Interference Mitigation

MPG restores communication range and mitigates RF interference through incorporation of Integrated Cosite Equipment (ICE), which, when installed between your radios and antennas, increases dynamic range, protects your receivers, and purifies your transmit signals.
