ISO 9001:2000 Certified



Planar Monolithics Industries, Inc. is very proud to announce that effective December 17, 2003 PMI has become ISO 9001:2000 Certified for the following scope of registration: Research, Development, Custom Design and Manufacture of RF/ Microwave Components, Super Components and Subsystems, in the DC to 40 GHz Frequency Range.  Please click here to see PMI's ISO Certificate.



PMI Model Number PS-12-360-QQ1470 is a 1 to 2 GHz, Digitally Controlled Analog Phase Shifter with Capability for Phase Shifting from 0 to 360 Degrees.  The unit consists of an analog phase shifter and a Digital-to-Analog Converter.  Eight Logic Input lines allow 256 discrete values of phase.

The PMI Model Number PS-12-360-QQ1470 is an example of a form fit and function design to reproduce an old design.  A more compact design is possible:

  1 to 2 GHz, 3.5" x 2.0" x 0.5", with new driver board design
  2 to 4 GHz, 3.0" x 2.0" x 0.5", with new driver board design
  4 to 8 GHz, 3.0" x 2.0" x 0.5", with new driver board design
  8 to 18 GHz, 2.0" x 3.0" x 0.5", shorter RF and new driver board
                                            design mounted in other direction

This particular unit operates over 1 to 2 GHz with 360˚ minimum phase shift.  An 8 bit digital control sets the phase with 1.4˚ resolution and switching time is 200 nS.  Options include 12 bit or analog voltage control.  Mid band insertion loss is typically 4 dB and worst case insertion loss over the full band is 6 dB.  Operating temperature is from -40˚ to 85˚ C.
