LTC5548 2GHz to 14GHz Microwave Mixer with Wideband DC6GHz IF Fea T Descrip T n Upconversion or Downconversion The LTC 5548 is a high performance, microwave double n High IIP3: +24.4dBm at 5.8GHz balanced passive mixer that can be used for frequency upconversion or downconversion. The device is similar +21.4dBm at 9GHz n to the LTC5549, but with a broadband, differential DC to 7.1dB Conversion Loss at 5.8GHz n 6GHz IF port. The LTC5548 is recommended for applica- +15.2dBm Input P1dB at 5.8GHz n tions where the IF frequency range extends below 500MHz. Integrated LO Buffer: 0dBm LO Drive n For applications where the IF frequency is always above Selectable Integrated LO Frequency Doubler 500MHz, the LTC5549 is recommended, since it includes n Low LO-RF Leakage: <30dBm an integrated IF balun. n 50 Wideband Matched RF and LO Ports n 3.3V/120mA Supply The LTC5548s mixer and integrated RF balun are opti- n Fast Turn ON/OFF for TDD Operation mized to cover the 2GHz to 14GHz RF frequency range. n 3mm 2mm, 12-Lead QFN Package The device includes an integrated LO amplifier optimized for the 1GHz to 12GHz frequency range, requiring only 0dBm drive. The device also includes an integrated LO a T frequency doubler, which can be enabled or disabled with n Microwave Transceivers a CMOS-compatible control pin. n Wireless Backhaul The LTC5548 delivers exceptionally high IIP3 and P1dB, n Point-to-Point Microwave in addition to very low LO to RF and LO to IF leakages. n Phased-Array Antennas The part also offers high integration in a small package. n C, X and Ku Band RADAR L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Test Equipment Technology Corporation.
