Equipped with the high performance parameters of the PicoFlexor, the PicoFlexor Transceiver adds a transmit capability.

In a miniature, tactical software-defined radio (SDR) platform, the PicoFlexor Transceiver integrates a transmitter with a high-performance SIGINT superheterodyne receiver in a single, low size, weight and power module.

With its open SDR architecture, the PicoFlexor Transceiver can be configured using open frameworks, such as GNU Radio and REDHAWK, to fit customer-specific application requirements. This customization enables the unit to perform in systems for both military and commercial operations including electronic attack, situational awareness, geo-location and spectrum monitoring.

The PicoFlexor Transceiver is backed by a standard three year warranty (some restrictions may apply). We are committed to providing outstanding product reliability and support, so you can focus on mission success.
