Rainbow Electronics MAX7036 - Manual

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 pack-
age with an exposed pad and is specified over the
AEC-Q100 Level 2 (-40°C to +105°C) temperature
range.
