MAX7034AUI+

The MAX7034AUI+ is a 315MHz/434MHz ASK Superheterodyne receiver in 28 pin TSSOP package. The MAX7034 fully integrated low power CMOS superheterodyne receiver is ideal for receiving amplitude shift keyed (ASK) data in the 300MHz to 450MHz frequency range (including the popular 315MHz and 433.92MHz frequencies). The receiver has an RF sensitivity of -114dBm. With few external components and a low-current power-down mode, it is ideal for cost-sensitive and power-sensitive applications typical in the automotive and consumer markets. The MAX7034 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 analogue baseband data-recovery circuitry.
