Product Details

The LTC5567 is optimized for RF downconverting mixer applications that require wide IF bandwidth. The part is also a pin-compatible upgrade to the LT5557 active mixer, offering higher linearity and 1dB compression, wider bandwidth, and lower output spurious levels. Integrated RF and LO transformers and LO buffer amplifiers allow a very compact solution.

The RF input is 50Ω matched from 1.4GHz to 3GHz, and easily matched for higher or lower RF frequencies with simple external matching. The LO input is 50Ω matched from 1GHz to 4GHz, even when the IC is disabled. The LO input is easily matched for higher or lower frequencies, as low as 300MHz, with simple external matching. The low capacitance differential IF output is usable up to 2.5GHz.

Applications

  • Wireless Infrastructure Receivers
  • DPD Observation Receivers
