LTC5567 300MHz to 4GHz Active Downconverting Mixer with Wideband IF Fea T Descrip T n High IIP3: +26.9dBm at 1950MHz The LTC 5567 is optimized for RF downconverting mixer n 1.9dB Conversion Gain applications that require wide IF bandwidth. The part is n Low Noise Figure: 11.8dB at 1950MHz also a pin-compatible upgrade to the LT5557 active mixer, n 16.5dB NF Under 5dBm Blocking offering higher linearity and 1dB compression, wider n Low Power: 294mW bandwidth, and lower output spurious levels. Integrated n Wide IF Frequency Range Up to 2.5GHz RF and LO transformers and LO buffer amplifiers allow a n LO Input 50 Matched when Shutdown very compact solution. n 40C to 105C Operation (T ) C The RF input is 50 matched from 1.4GHz to 3GHz, and n Very Small Solution Size easily matched for higher or lower RF frequencies with n Pin Compatible with LT5557 simple external matching. The LO input is 50 matched n 16-Lead (4mm 4mm) QFN package from 1GHz to 4GHz, even when the IC is disabled. The LO input is easily matched for higher or lower frequencies, as a T low as 300MHz, with simple external matching. The low capacitance differential IF output is usable up to 2.5GHz. n Wireless Infrastructure Receivers L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n DPD Observation Receivers Technology Corporation.
