Application Scenarios & Design Considerations

DUAL TONE and POLARITY SWITCH LNB MULTIPLEX CONTROLLER

Alternative Part Number

  • DSLNB2004 --: Diodes Incorporated acquired Zetex and continues to offer the same LNB controller function under its own naming, making it a direct functional replacement.
  • LT5534 --: RF power detector/LNB control IC with comparable gain and detection characteristics, suitable as a functional substitute in LNB control circuits.
  • MAX2015 --: Logarithmic RF detector with similar signal detection range, usable as an alternative for LNB signal sensing applications.
  • AD8317 --: Wideband logarithmic RF detector that can serve as an alternative signal-detection solution for LNB control circuits, from a different product family.
