___________Applications Information  
Layout Considerations  
A properly designed PC board is an essential part of  
any RF/microwave circuit. Keep RF signal lines as short  
as possible to reduce losses, radiation, and induc-  
tance. Use separate, low-inductance vias to the ground  
plane for each ground pin. For best performance, sol-  
der the exposed pad on the bottom of the device pack-  
age evenly to the board ground plane.  
Bias Circuitry  
The linearity and supply current of the MAX2683/  
MAX2684 are externally programmable with a single  
resistor, R  
, from BIAS to GND. A nominal resistor  
BIAS  
value of 1.2kwill set an IIP3 of +9dBm and a supply  
current of 55mA. Decreasing the resistor value  
improves linearity at the cost of increased supply cur-  
rent. Increasing the resistor value decreases supply  
current while degrading linearity. Use resistor values in  
the range of 820kto 2k.  
Power-Supply and ENX2 Bypassing  
Proper voltage-supply bypassing is essential for high-  
frequency circuit stability. Bypass V  
with a 10µF  
CC  
capacitor in parallel with a 100pF capacitor located as  
close to the V pin as possible.  
CC  
Bypass ENX2 with a 100pF capacitor to ground to mini-  
mize noise injected into the LO doubler cell. Use a  
series resistor (typically 1.2k) to further reduce cou-  
pling of high-frequency signals into the ENX2 pin.
