Datasheet Linear Technology LTC6410IUD-6#PBF

LTC6410-6
Low Distortion, Low Noise
Differential IF Amplifier with
Configurable Input Impedance
DESCRIPTION FEATURES n n n The LTC®6410-6 is a low distortion, low noise differential
IF amplifier with configurable input impedance designed
for use in applications from DC to 1.4GHz. The LTC6410-6
has 6dB of voltage gain. The LTC6410-6 is an excellent
choice for interfacing active mixers to SAW filters. It features an active input termination that allows a customized
input impedance for an optimum interface to differential
active mixers. This feature provides additional power gain
because of the impedance conversion and improved noise
performance when compared to traditional 50Ω interface
circuits. The LTC6410-6 drives a differential 50Ω load
directly with low distortion, which is suitable for driving
SAW filters and other 50Ω signal chain blocks. 1.4GHz –3dB Bandwidth
Fixed Voltage Gain of 6dB (50Ω System)
Configurable Input Impedance Allows:
Simple Interface to Active Mixers
Improved Noise Performance
Wide 2.8V to 5.25V Supply Range
Low Distortion:
36dBm OIP3 (70MHz) …
