Series 91 and 92 Miniature Broadband SP4T Switches

pplication Notes for RF Switches

MODELS 9140-500 and 9240-500

These switches provide high-performance characteristics over a multi-octave frequency range. Model 9140-500 covers the 1 to 18 GHz frequency range while the Model 9240-500 covers the 0.2 to 4 GHz range. Their description and operation are the same as that for the Models 9120-500 and 9220-500 SP2T switches.

MODELS 9140T-500, 9140W-500 and 9240T-500

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

MODELS 9140AH-500 and 9140AHT-500

These switches are the same as the 9120AH-500 and the 9120AHT-500 except for the number of ports.

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
  • Rise and fall times as fast as
    10 nsec
  • Reflective and Non-reflective models
  • Low VSWR and Insertion loss
  • Isolation: up to 60 dB
  • Miniature size, light weight
