LTC6410-6 Low Distortion, Low Noise Differential IF Amplifi er with Confi gurable Input Impedance
FEATURES DESCRIPTION
n
1.4GHz –3dB Bandwidth
The LTC®6410-6 is a low distortion, low noise differential n
Fixed Voltage Gain of 6dB (50
Ω
System)
IF amplifi er with confi gurable input impedance designed n
Confi gurable Input Impedance Allows:
for use in applications from DC to 1.4GHz. The LTC6410-6
Simple Interface to Active Mixers
has 6dB of voltage gain. The LTC6410-6 is an excellent
Improved Noise Performance
choice for interfacing active mixers to SAW fi lters. It fea- n
Wide 2.8V to 5.25V Supply Range
tures an active input termination that allows a customized n
Low Distortion:
input impedance for an optimum interface to differential
36dBm OIP3 (70MHz)
active mixers. This feature provides additional power gain
33dBm OIP3 (140MHz)
because of the impedance conversion and improved noise
31dBm OIP3 (300MHz)
performance when compared to traditional 50Ω interface n
Low Noise:
circuits. The LTC6410-6 drives a differential 50Ω load
11dB NF (50
Ω
ZIN)
directly with low distortion, which is suitable for driving
8dB NF (200
Ω
ZIN)
SAW fi lters and other 50Ω signal chain blocks. n
