Phase Trimmers

Phase Trimmers


Pasternack RF phase trimmers are adjustable passive microwave devices

designed for RF applications where phase match between two cables is needed

for proper system performance. Depending on the application, minor adjustments in

phase may be required for the phase trimmer to ensure peak performance of the RF

system. Variable RF phase trimmers from Pasternack allow the user to make precise manual

adjustments to the phase without degrading the signal.


50 Ohm RF phase trimmers from Pasternack 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. Our 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 our phase trimmers for RF is 0.5 dB. Many of our analog RF phase trimmers are REACH compliant.
