MAX7036
EVALUATION KIT AVAILABLE
300MHz to 450MHz ASK Receiver
with Internal IF Filter
General Description
The MAX7036 low-cost receiver is designed to receive
amplitude-shift-keyed (ASK) and on-off-keyed (OOK) data
in the 300MHz to 450MHz frequency range. The receiver
has an RF input signal range of -109dBm to 0dBm.
The MAX7036 requires few external components and has
a power-down pin to put it in a low-current sleep mode,
making it ideal for cost- and power-sensitive applications.
The low-noise amplifier (LNA), phase-locked loop (PLL),
mixer, IF filter, received-signal-strength indicator (RSSI),
and baseband sections are all on-chip. The MAX7036
uses a very-low intermediate frequency (VLIF) architecture.
The MAX7036 integrates the IF filter on-chip and, therefore,
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 (-40°C to +105°C) temperature range.
