Teseq / IFI

Teseq / IFI

Teseq / IFI represents the high-power RF and microwave amplifier product line originating from IFI (Instruments for Industry), a long-established US manufacturer of broadband amplifiers used in EMC immunity testing, radar cross-section measurement, electronic warfare research, and antenna characterization. IFI's amplifier lines were subsequently marketed under the Teseq / IFI brand following Teseq's acquisition and portfolio expansion.

The Teseq / IFI range includes solid-state broadband amplifiers covering frequencies from HF through several GHz, as well as traveling wave tube (TWT) amplifiers for higher microwave frequencies requiring greater output power. These amplifiers are characterized by wide instantaneous bandwidth, high gain, and the ability to sustain CW and pulsed operation in demanding test environments.

Key Product Lines

• RF Solid-State Amplifiers: Broadband amplifiers from HF through microwave frequencies for EMC radiated immunity testing per IEC 61000-4-3 and MIL-STD-461
• TWT Amplifiers: Traveling wave tube amplifiers covering 1 GHz to 18 GHz and beyond for high-power microwave signal generation in radar and electronic warfare test applications
• Microwave Amplifiers: High-gain amplifiers for antenna gain measurement, radar system testing, and satellite communication test environments

Industries Served

Teseq / IFI amplifiers are used in EMC test laboratories, aerospace and defense research facilities, radar system development programs, electronic warfare test ranges, and satellite and telecommunications test environments where high-power, wideband RF signal generation is required across broad frequency ranges.
