DESCRIPTIOU
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 distor-
tion 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 suppres-
sion requirements.
The device is designed to work over a supply voltage range
from 3.15V to 5.25V.
