High Linearity Mixer Applications
High Signal Level
Upconverting Mixer
The LT
®
5511 mixer is designed to meet the high linearity
requirements of cable TV infrastructure downstream trans-
mitters and wireless infrastructure transmit systems. The
IC includes a differential LO buffer amplifier driving a
double-balanced mixer. The LO, RF and IF ports can be
easily matched to a broad range of frequencies for differ-
ent applications. The high performance capability of the
LO buffer allows the use of a single-ended source, thus
eliminating the need for an LO balun.
The LT5511 mixer delivers +17dBm typical input 3rd
order intercept point at 950MHz, and +15.5dBm IIP3 at
1900MHz, with IF input signal levels of – 5dBm. The input
1dB compression point is typically +6dBm.
