LT5578
0.4GHz to 2.7GHz
High Linearity
Upconverting Mixer
FEATURES DESCRIPTION n The LTВ®5578 mixer is a high performance upconverting
mixer optimized for frequencies in the 0.4GHz to 2.7GHz
range. The single-ended LO input and RF output ports
simplify board layout and reduce system cost. The mixer
needs only –1dBm of LO power and the balanced design
results in low LO signal leakage to the RF output. At
1.95GHz operation, the LT5578 provides conversion gain
of –0.7dB, high OIP3 of 24.3dBm and a low noise floor of
–158dBm/Hz at a –5dBm RF output signal level. High Output IP3: 27dBm at 0.9GHz
24.3dBm at 1.95GHz
Low Noise Floor: –158dBm/Hz (POUT = –5dBm)
High Conversion Gain: 1.4dB at 0.9GHz
Noise Figure: 8.6dB
Low LO-RF Leakage: –43dBm
Single-Ended RF and LO Ports
Low LO Drive Level: –1dBm
Single 3.3V Supply
