Product Summary
The LT 5521 is a very high linearity mixer optimized for
low distortion and low LO leakage applications. The chip
includes a high speed LO buffer with single-ended input
and a double-balanced active mixer. The LT5521 requires
only –5dBm LO input power to achieve excellent distortion and noise performance, while reducing external drive
circuit requirements. The LO buffer is internally 50?
matched for wideband operation.
With a 250MHz input, a 1.7GHz LO and a 1.95GHz output
frequency, the mixer has a typical IIP3 of +24.2dBm,
–0.5dB conversion gain and a 12.5dB noise figure.
The LT5521 offers exceptional LO-RF isolation, greatly
reducing the need for output filtering to meet LO suppression requirements.
The device is designed to work over a supply voltage range
from 3.15V to 5.25V.
