Product Details
The MAX7033 fully integrated low-power CMOS super-heterodyne receiver is ideal for receiving amplitude shift-keyed (ASK) data in the 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. The MAX7033 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 MAX7033 also has a discrete one-step automatic gain control (AGC) that reduces the LNA gain by 35dB when the RF input signal exceeds -62dBm. The AGC circuitry offers an externally controlled hold feature.
The MAX7033 is available in 28-pin TSSOP and 32-pin TQFN packages and is specified over the extended (-40°C to +105°C) temperature range.
