NAME  
FUNCTION  
A1  
V
Supply Voltage. Bypass to ground with a 10pF capacitor as close as possible to the IC.  
CC  
RF Output/SHDN Input. RFOUT is internally matched to 50I and pulled up to V through a 1MI  
CC  
RFOUT  
resistor. SHDN is shared with the RFOUT bump. The devices are in active mode by default once

is applied. RFOUT(SHDN) can be pulled to a DC low through a 25kI resistor to shut down  
CC  
the IC.  
B1  
B2  
RFIN  
GND  
RF Input. Requires a DC-blocking capacitor and external matching components.  
Ground. Connect to the PCB ground plane.  
The value of the input coupling capacitor affects IIP3.  
Detailed Description  
A smaller coupling capacitor results in lower IIP3. The  
devices integrate an on-chip output matching to 50I at  
the output, eliminating the need for external matching  
components. Table 1 and Table 2 list typical device S  
The MAX2686L/MAX2693L are LNAs designed for GPS  
L1, Galileo, and GLONASS applications. The devices fea-  
ture an optional power-shutdown control mode to elimi-  
nate the need for an external supply switch. The devices  
achieve high gain and low noise figure in an ultra-small  
package ideal for space-sensitive applications. These  
integrated ICs eliminate the need for an external LDO.  
parameters and K values. Typical noise parameters are

shown in Table 3 and Table 4.  
Shutdown  
The devices include an optional shutdown feature to turn  
off the entire chip. The devices are placed in active mode  
Input and Output Matching  
The devices require an off-chip input matching. Only an  
inductor in series with a DC-blocking capacitor is needed  
to form the input matching circuit. The Typical Operating  
Circuit shows the recommended input-matching net-  
work. These values are optimized for the best simulta-  
neous gain, noise figure, and return loss performance.  
by default once V  
is applied, due to the on-chip pul-  
CC  
lup resistor to V  
at the RFOUT bump (shared with the  
CC  
SHDN input). To shut down the part, apply a logic-low  
to the RFOUT bump through an external resistor with an  
adequate value, e.g., 25kI, in order not to load the RF  
output signal during active operation.
