MAX7033EUI+

The MAX7033EUI+ is a 315MHz/433MHz ASK superheterodyne receiver in 28 pin TSSOP package. This fully integrated low power CMOS superheterodyne receiver is ideal for receiving amplitude shift keyed ASK data in 300MHz to 450MHz frequency range. The receiver has an RF input signal range of -114dBm to 0dBm. With few external components and a low current power-down mode, it is ideal for cost sensitive and power sensitive applications typical in consumer markets. It 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. It has a discrete one-step automatic gain control (AGC) that reduces LNA gain by 35dB when the RF input signal exceeds -62dBm. It is used in garage door openers, local telemetry, wireless sensors and remote control applications.
