315MHz/433MHz ASK Superheterodyne
Receiver with AGC Lock
Layout Considerations
A properly designed PCB is an essential part of any
RF/microwave circuit. On high-frequency inputs and
outputs, use controlled-impedance lines and keep
them as short as possible to minimize losses and radia-
tion. At high frequencies, trace lengths that are on the
order of λ /10 or longer act as antennas.
Keeping the traces short also reduces parasitic induc-
tance. Generally, 1in of a PCB trace adds about 20nH
of parasitic inductance. The parasitic inductance can
have a dramatic effect on the effective inductance of a
passive component. For example, a 0.5in trace con-
necting a 100nH inductor adds an extra 10nH of induc-
To reduce the parasitic inductance, use wider traces
and a solid ground or power plane below the signal
traces. Also, use low-inductance connections to
ground on all GND pins, and place decoupling capaci-
tors close to all power-supply pins.
Control Interface Considerations
When operating the MAX7033 with a +4.5V to +5.5V
supply voltage, the SHDN and AC pins can be driven
by a microcontroller with either 3V or 5V interface logic
levels. When operating the MAX7033 with a +3.0V to
+3.6V supply, only 3V logic from the microcontroller is
allowed.
