The LT5522 is an active downconverting mixer optimized for high linearity downconverter applications. It features an internal on-chip RF input transformer, 50Ω single-ended RF and LO ports, high input IP3, low power consumption, etc.
The LT5522 active downconverting mixer is optimized for high‑linearity applications such as cellular, PCS, UMTS, CATV and 2.4 GHz ISM infrastructure. It integrates an on‑chip RF input transformer, a low‑power LO buffer, and requires very few external components.
Typical performance includes conversion gain from –2 dB to +0.2 dB across the band, IIP3 up to 22.3 dBm, and single‑sideband noise figures as low as 12.5 dB at 900 MHz. The device is supplied in a 16‑lead plastic QFN package and operates from 4.5 V to 5.25 V.
