MILLIMETERWAVE COMPONENTS

MILLIMETERWAVE COMPONENTS

Recent advances have been made by Pasquali Microwave Systems in the manufacturing of millimeter-wave components through electroforming. Electroforming is a metal forming process that forms thin parts through the electroplating process. The part is produced by plating a metal skin onto a base form, known as a mandrel, which is removed after plating. The main advantage of electroforming is that it reproduces the external shape of the mandrel within a tolerance of one micron.

22 GHz Polarizer

22 GHz Polarizer

This device separates two incoming circular polarization (a Left-Handed Circular Polarization and a Right-Handed Circular Polarization) into two orthogonal linear polarizations. It is composed of two parts: a Differential Phase Shifter and an Orthomode Transducer.
The RF specifications are the following:
o Frequency Range: 18-26GHz
o Return loss: < -20dB
o Cross talk: >20dB (19-25GHz) ; >35dB@22GHz>

Thanks to the high precision of electroforming process the device meets all the RF requirements.

30 and 44 GHz “flight model” waveguides for ESA Planck satellite

“Flight model” waveguides are compliant with RF, environmental (vibration) and outgassing requirements for space application.

W-band OMT

W-band OMT

This device is a full-band orthomode transducer (OMT) for the WR10 frequency band (75 – 110 GHz). It is manufactured by PMS through the electroforming process.
