A new wide bandwidth active upconverting mixer, the LT5578 from Linear Technology, delivers high dynamic range performance from 400MHz to 2.7GHz, supporting all of the allocated LTE (Long-Term Evolution) broadband wireless services. At 900MHz, the mixer offers 27dBm Output IP3 linearity and best-in-class noise floor of -160.5dBm/Hz at an output level of -5dBm, enabling outstanding transmitter dynamic range. In addition, the mixer has 1.4dB conversion gain with integrated RF balun transformers that provide a single-ended RF output and LO (Local Oscillator) input to simplify designs while reducing external component count. Moreover, the device’s LO input is internally buffered, requiring a drive level of only -1dBm. This results in an outstanding LO-to-RF leakage of -43dBm.
