LTC5549 2GHz to 14GHz Microwave Mixer with Integrated LO Frequency Doubler Fea T Descrip T n Upconversion or Downconversion The LTC 5549 is a general purpose passive double- n High IIP3: +28.2dBm at 5.8GHz balanced mixer that can be used for upconversion or downconversion. The RF port is designed for the 2GHz to +22.8dBm at 12GHz n 14GHz band and the IF port is optimized for 500MHz to 8.0dB Conversion Loss at 5.8GHz n 6GHz operation. An integrated LO buffer amplifier supports +14.3dBm Input P1dB at 5.8GHz n LO frequencies from 1GHz to 12GHz, requiring only 0dBm Integrated LO Buffer: 0dBm LO Drive n LO power. The LTC5549 delivers high IIP3 and input P1dB Bypassable Integrated LO Frequency Doubler with low power consumption. n Low LO-RF Leakage: <30dBm n 50 Single-Ended RF, LO and IF Ports An internal LO frequency doubler can be enabled by a n 3.3V/115mA Supply CMOS-compatible digital control pin, allowing operation n Fast Turn ON/OFF for TDD Operation with a lower, one-half LO input frequency. This allows the n 2mm 3mm, 12-Lead QFN Package mixers LO port to be used with existing synthesizers, such as the LTC6946 and LTC6948 family. The LTC5549s high level of integration minimizes the total a T solution cost, board space and system level variation with n Microwave Transceivers its 2mm 3mm package size. n Wireless Backhaul L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Point-to-Point Microwave Technology Corporation.
