FEATURES  
DESCRIPTIO  
The LT®5519 mixer is designed to meet the high linearity  
requirements of wireless and cable infrastructure trans-  
mission systems. A high speed, internally 50matched,  
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,  
whilereducingsystemcost, componentcount, boardarea  
and system-level variations. The IF port can be easily  
matched to a broad range of frequencies for use in many  
different applications.  
Wide RF Frequency Range: 0.7GHz to 1.4GHz  
17.1dBm Typical Input IP3 at 1GHz  
On-Chip RF Output Transformer  
On-Chip 50Matched LO and RF Ports  
Single-Ended LO and RF Operation  
Integrated LO Buffer: –5dBm Drive Level  
Low LO to RF Leakage: – 44dBm Typical  
Noise Figure: 13.6dB  
Wide IF Frequency Range: 1MHz to 400MHz  
Enable Function with Low Off-State Leakage Current  
Single 5V Supply  
Small 16-Lead QUFN Plastic Package  
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.
