LTC5553 3GHz to 20GHz Microwave Mixer Fea T Descrip T n Upconversion or Downconversion The LTC 5553 is a high performance, microwave double n High IIP3: +24.3dBm at 10GHz balanced passive mixer that can be used for frequency +21.5dBm at 17GHz upconversion or downconversion. n 9dB Conversion Loss at 10GHz The LTC5553s mixer and integrated RF balun are optimized n +16dBm Input P1dB at 10GHz to cover the 3GHz to 20GHz RF frequency range. The n Integrated LO Buffer: 0dBm LO Drive device includes an integrated LO amplifier optimized for n Low LO-RF Leakage: <25dBm the 1GHz to 20GHz frequency range, requiring only 0dBm n 50 Wideband Matched RF, LO and IF Ports drive. The integrated IF balun is optimized to cover a very n 3.3V/132mA Supply wide, 500MHz to 9GHz, frequency range while providing n Fast Turn ON/OFF for TDD Operation a single-ended 50 interface. n 3mm 2mm, 12-Lead QFN Package The LTC5553 delivers exceptionally high IIP3 and P1dB, in addition to low LO to RF and LO to IF leakages. The part also offers a high level of integration in a small package. a T L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Analog n 5G Broadband Wireless Access Devices, Inc.
