Series 91 and 92 Miniature Broadband SP5T Switches

Application Notes for RF Switches

MODELS 9150-500 and 9250-500

These switches provide high-performance characteristics over a multi-octave frequency range. The Model 9150-500 covers the 1 to 18 GHz frequency range while the Model 9250-500 covers the 0.2 to 4 GHz range. This description and operation are the same as that for the Models 9120-500 and 9220-500 SP2T switches.

MODELS 9150T-500, 9150W-500, and 9250T-500

These switches are non-reflective versions of the switches described above.

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.

SERIES G91 and G92

Operating from +5 and +15V power supplies only, the G-series switches provide high performance characteristics at relatively high speeds over multi-octave frequency ranges. The series includes low Insertion loss and high isolation models in both reflective and non-reflective configurations. Series G91 units cover the frequency range of 1 to 18 GHz; Series G92 units cover the frequency range of 0.2 to 4 GHz. The design is based on an integrated circuit assembly of PIN diodes mounted in a microstrip transmission line as shown below. The currents required to switch the ports ON or OFF are provided by the integrated driver, which is controlled by external TTL logic signals.

  • Frequency range (Series 91):
    1 to 18 GHz
  • Frequency range (Series 92):
    0.2 to 4 GHz
  • Reflective and Non-reflective models
  • Low VSWR and Insertion loss
  • Isolation: up to 60 dB
  • Miniature size, light weight

*Special-order product. Consult factory before ordering.

NOTE 
(1) Models prefixed with "F" or "G" are equipped with integrated TTL-compatible drivers; models without the "F" or "G" prefix are current-controlled units and are furnished without drivers; models suffixed with "T" or "W" are non-reflective except a high VSWR will be present at the common port if all other ports are OFF.
