в–  The LTВ®5502 is a 70MHz to 400MHz monolithic integrated
quadrature IF demodulator. It consists of an IF limiter,
quadrature down mixers, integrated lowpass filters, and
divide-by-two LO buffers. The demodulator provides all
building blocks for demodulation of I and Q baseband
signals with a single supply voltage of 1.8V to 5.25V. The
IF limiter has 84dB small-signal gain, and a built-in receive
signal strength indicator (RSSI) with over 90dB linear
range. The input referred noise-spectral-density is …
