General Description
The MAX1473 fully integrated low-power CMOS super-
heterodyne receiver is ideal for receiving amplitude-
shift-keyed (ASK) data in the 300MHz to 450MHz
frequency range. Its signal range is from -114dBm to
0dBm. With few external components and a low-current
power-down mode, it is ideal for cost- and power-sensi-
tive applications typical in the automotive and consumer
markets. The chip consists of a low-noise amplifier
(LNA), a fully differential image-rejection mixer, an on-
chip phase-locked-loop (PLL) with integrated voltage-
controlled oscillator (VCO), a 10.7MHz IF limiting
amplifier stage with received-signal-strength indicator
(RSSI), and analog baseband data-recovery circuitry.
The MAX1473 also has a discrete one-step automatic
gain control (AGC) that drops the LNA gain by 35dB
when the RF input signal is greater than -57dBm.
The MAX1473 is available in 28-pin TSSOP and 32-pin
thin QFN packages. Both versions are specified for the
extended (-40°C to +85°C) temperature range.
