MAX1473 Datasheet | Maxim Integrated

.. 19-2748; Rev 3; 11/03 315MHz/433MHz ASK Superheterodyne Receiver with Extended Dynamic Range General Description The MAX1473 fully integrated low-power CMOS superheterodyne receiver is ideal for receiving amplitudeshift-keyed (ASK) data in the 300MHz to 450MHz frequency range. Its signal range is from -114dBm to 0dBm. With few external ponents and a low-current power-down mode, it is ideal for cost- and power-sensitive applications typical in the automotive and consumer markets. The chip consists of a low-noise amplifier (LNA), a fully differential image-rejection mixer, an onchip phase-locked-loop (PLL) with integrated voltagecontrolled oscillator (VCO), a 10.7MHz...
