n 24-Lead 4mm Г— 4mm QFN Package The LTCВ®5585 is a direct conversion quadrature demodulator optimized for high linearity receiver applications in
the 400MHz to 4GHz frequency range. It is suitable for
communications receivers where an RF signal is directly
converted into I and Q baseband signals with bandwidth
of 530MHz or higher. The LTC5585 incorporates balanced …
