LTC5567 Down-converting Mixer



Linear Technology's 300 MHz to 4 GHz active down-converting mixer with wideband IF


Linear Technology LTC5567 Downconverting Mixer Linear Technology's LTC®5567 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 1 dB compression, wider bandwidth, and lower output spurious levels. Integrated RF and LO transformers, along with LO buffer amplifiers, allow a very compact solution.

The RF input is 50 Ω matched from 1.4 GHz to 3 GHz, and easily matched for higher or lower RF frequencies with simple external matching. The LO input is 50 Ω matched from 1 GHz to 4 GHz, even when the IC is disabled.  LTC5567 Datasheet
