SERIES 91 and 92
Series 91 and 92 switches provide high performance characteristics over a multi-octave range. Series 91 models cover the frequency range of 1 to 18 GHz, while Series 92 models cover the range from 0.2 to 4.0 GHz. These miniature switches measure only 0.75 x 0.69 x 0.38 inches.

Both series use an integrated circuit assembly of up to four PIN diodes mounted in a microstrip transmission line. The circuit configuration is shown below.

RF Schematic Diagram Series 91 and 92 SPST Switches
 
Application of a positive current to the bias terminal switches the unit OFF since the diodes are biased to a low resistance value. With zero or negative voltage at the bias terminal, the diodes are biased to high resistances and the unit is switched ON. Maximum rise and fall times are less than 10 nsec.

 

SERIES F91 AND F92
The Series F91 and F92 switches are the same as the corresponding Series 91 and 92 models except the units are equipped with integrated drivers, and the dimensions of the units are 0.75 x 0.75 x 0.38 inches. The proper current required to switch the unit ON or OFF is provided by the integral driver which requires +5 and -12 to -15 volt power supplies and is controlled by an external logic signal.
  • Frequency range (Series 91):
    1 to 18 GHz
  • Frequency range (Series 92):
    0.2 to 4 GHz
  • Low VSWR and Insertion loss
  • Up to 80 dB isolation
  • Less than 10 nsec rise and fall time
  • Miniature size, light weight
