LTC5552 3GHz to 20GHz Microwave Mixer with Wideband DC to 6GHz IF FEATURES DESCRIPTION n Integrated LO Buffer: 0dBm LO Drive The LTC 5552 is a high performance, microwave double n 50 Wideband Matched RF and LO Ports balanced passive mixer that can be used for frequency n Wide IF Bandwidth: DC to 6GHz upconversion or downconversion. The device is similar n Upconversion or Downconversion to the LTC5553, but with a broadband, differential DC to n High IIP3: 6GHz IF port. The LTC5552 is recommended for applica- n +22.5dBm at 10GHz tions where the IF frequency range extends below 500MHz. n +18.3dBm at 17GHz For applications where the IF frequency is always above n +14.6dBm Input P1dB at 10GHz 500MHz, the LTC5553 is recommended, since it includes n 8dB Conversion Loss at 10GHz an integrated IF balun. n 3.3V/132mA Supply The mixer and integrated RF balun are optimized to cover n Fast Turn ON/OFF for TDD Operation the 3GHz to 20GHz RF frequency range. The integrated LO n 3mm 2mm, 12-Lead QFN Package amplifier is optimized for the 1GHz to 20GHz frequency range, requiring only 0dBm drive. APPLICATIONS The part delivers high IIP3 and P1dB, low LO leakage and n 5G Broadband Wireless Access high integration in a small package. n Microwave Transceivers n Wireless Backhaul Electrostatic Sensitive Device n Point-to-Point Microwave Observe Handling Precautions n Phased-Array Antennas ESD Sensitivity: n C, X and Ku Band RADAR HBM = Class 0 on Pin 11 n Test Equipment Class 1C All Other Pins n Satellite Modems CDM = 500V All Pins L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of AnalogDevices, Inc.
