The Spectrum Elektrotechnik GmbH LS-P150-HFHM is a precision phase-adjustable adapter designed for use in RF and microwave test and measurement systems. Manufactured by Spectrum Elektrotechnik GmbH of Munich, Germany — a leading developer of RF and microwave components covering DC to 65 GHz — this inline adapter allows fine, repeatable phase trimming across an ultra-wide frequency range from DC to 50 GHz. It is suited to applications including antenna phased-array alignment, vector network analyser calibration, radar and defence systems, satellite communications, and phase-matched test setups.

The air-line design principle employed by Spectrum Elektrotechnik yields low insertion loss and excellent VSWR performance. The rotating mechanism provides up to 7 turns of smooth adjustment, enabling a minimum of 400° of phase shift at 50 GHz with a nominal sensitivity of 1.2°/GHz per turn. The stainless steel body ensures durability across a wide operating temperature range.
