LT5516
800MHz to 1.5GHz Direct
Conversion Quadrature Demodulator U FEATURES DESCRIPTIO в–  The LT В®5516 is an 800MHz to 1.5GHz direct conversion
quadrature demodulator optimized for high linearity receiver applications. It is suitable for communications
receivers where an RF or IF signal is directly converted into
I and Q baseband signals with bandwidth up to 260MHz.
The LT5516 incorporates balanced I and Q mixers, LO
buffer amplifiers and a precision, high frequency quadrature generator. в–
