TYPICAL APPLICATION
DESCRIPTION
400MHz to 3.7GHz
5V High Signal Level
Downconverting Mixer
The LT
®
5527 active mixer is optimized for high linearity,
wide dynamic range downconverter applications. The
IC includes a high speed differential LO buffer amplifi er
driving a double-balanced mixer. Broadband, integrated
transformers on the RF and LO inputs provide single-ended
50Ω interfaces. The differential IF output allows convenient
interfacing to differential IF fi lters and amplifi ers, or is
easily matched to drive 50Ω single-ended, with or without
an external transformer.
The RF input is internally matched to 50Ω from 1.7GHz
to 3GHz, and the LO input is internally matched to 50Ω
from 1.2GHz to 5GHz. The frequency range of both ports
is easily extended with simple external matching. The IF
output is partially matched and usable for IF frequencies
up to 600MHz.
The LT5527’s high level of integration minimizes the total
solution cost, board space and system-level variation.
