Phase Trimmers

Phase Trimmers


RF phase trimmers are adjustable passive microwave devices designed for

applications where phase match between two cables is needed for proper RF system

performance. Depending on the application, minor adjustments in phase may be

required for the phase trimmer to ensure peak performance of the system. Pasternack

variable RF phase trimmers allow the user to make precise manual adjustments to the phase

without degrading the signal.


50 Ohm RF phase trimmers are designed with SMA connectors or can be ordered with a SMA to RG405 coax (.085" semi-rigid, solder attachment) option. Our analog phase trimmers have operating frequencies ranging from DC to 18 GHz. Pasternack RF broadband phase trimmers have a phase range of 0° to 360° and a phase adjustment of 10° per GHz depending on type and style. Maximum insertion loss for all of the phase trimmer product line is 0.5 dB. Many of our analog RF phase trimmers are REACH compliant.
