LTC5584 - 30MHz to 1.4GHz IQ Demodulator

General Description

The LTC®5584 is a direct conversion quadrature demodulator optimized for high linearity receiver applications in the 30MHz to 1.4GHz frequency range.

It is also usable in the 10MHz to 30MHz and 1.4GHz to 2GHz ranges with reduced performance.
