High Linearity
Upconverting Mixer
The LT
5519 mixer is designed to meet the high linearity
requirements of wireless and cable infrastructure trans-
mission systems. A high speed, internally 50
matched,
LO amplifier drives a double-balanced mixer core, allow-
ing the use of a low power, single-ended LO source. An RF
output transformer is integrated, thus eliminating the
need for external matching components at the RF output,
while reducing system cost, component count, board area
and system-level variations. The IF port can be easily
matched to a broad range of frequencies for use in many
different applications.
The LT5519 mixer delivers +17.1dBm typical input 3rd
order intercept point at 1GHz with IF input signal levels of
–10dBm. The input 1dB compression point is typically
+5.5dBm. The IC requires only a single 5V supply.
