EVALUATION KIT AVAILABLE MAX7036 300MHz to 450MHz ASK Receiver with Internal IF Filter General Description Benefits and Features The MAX7036 low-cost receiver is designed to receive ASK/OOK Modulation amplitude-shift-keyed (ASK) and on-off-keyed (OOK) data < 250s Enable Turn-On Time in the 300MHz to 450MHz frequency range. The receiver On-Chip PLL, VCO, Mixer, IF, Baseband has an RF input signal range of -109dBm to 0dBm. Low IF (200kHz Nominal) The MAX7036 requires few external components and has a power-down pin to put it in a low-current sleep mode, 5.5mA DC Current making it ideal for cost- and power-sensitive applications. 1A Standby Current The low-noise amplifier (LNA), phase-locked loop (PLL), 3.3V/5V Operation mixer, IF filter, received-signal-strength indicator (RSSI), Small 20-Pin Thin QFN Package with an Exposed and baseband sections are all on-chip. The MAX7036 Pad uses a very-low intermediate frequency (VLIF) architecture. The MAX7036 integrates the IF filter on-chip and, therefore, AEC-Q100 Qualified eliminates an external ceramic filter, reducing the bill-of- materials cost. The device also contains an on-chip automatic gain control (AGC) that reduces the LNA gain by 30dB when the input signal power is large. The MAX7036 operates from either a 5V or a 3.3V power supply and draws 5.5mA (typ) of current. The MAX7036 is available in a 20-pin thin QFN package with an exposed pad and is specified over the AEC-Q100 Level 2 (-40C to +105C) temperature range.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 3.3V DC Electrical Characteristics (Typical Application Circuit, 50 system impedance, V = V = V = 3.0V to 3.6V, f = 300MHz to 450MHz, T = -40C to AVDD DVDD DD RF A +105C, unless otherwise noted.
