The LTC5540 is part of a family of high dynamic range, high gain passive downconverting mixers covering the 600MHz to 4GHz frequency range. The LTC5540 is optimized for 0.6GHz to 1.3GHz RF applications. The LO frequency must fall within the 0.7GHz to 1.2GHz range for optimum performance. A typical application is a LTE or GSM receiver with a 700MHz to 915MHz RF input and high-side LO.

The LTC5540 is designed for 3.3V operation, however; the IF amplifier can be powered by 5V for the highest P1dB. An integrated SPDT LO switch with fast switching accepts two active LO signals, while providing high isolation.

The LTC5540’s high conversion gain and high dynamic range enable the use of lossy IF filters in high-selectivity receiver designs, while minimizing the total solution cost, board space and system-level variation.

Applications

  • Wireless Infrastructure Receivers (LTE, GSM, W-CDMA)
  • Point-to-Point Microwave links
  • High Dynamic Range Downmixer Applications
