High Signal Level

Upconverting Mixer

FEATURES

DESCRIPTIO

The LT^®5511 mixer is designed to meet the high linearity

requirementsofcableTVinfrastructuredownstreamtrans-

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.
