FUNCTION
Supply Voltage. Bypass to ground with a 10pF capacitor as close as possible to the IC.
RF Output/ SHDN Input. RFOUT is internally matched to 50 I and pulled up to V CC through a 1M I
resistor. SHDN is shared with the RFOUT bump. The device is in active mode by default once V CC
is applied. RFOUT( SHDN ) can be pulled to a DC low through a 25k I resistor to shut down the IC.
RF Input. Requires a DC-blocking capacitor and external matching components.
Ground. Connect to the PCB ground plane.
Detailed Description
The MAX2691 LNA is designed for GPS L2 applications.
The device features a power-shutdown control mode
to eliminate the need for an external supply switch.
The device achieves high gain, low noise figure, and
excellent linearity.
Input and Output Matching
The MAX2691 requires an off-chip input match. Only an
inductor in series with a DC-blocking capacitor is needed
to form the input matching circuit. The Typical Application
Circuit shows the recommended input-matching network.
These values are optimized for the best simultane-
ous gain, noise figure, and return loss performance.
Reducing the input coupling capacitor results in a lower
IIP3. The device integrates an on-chip output matching
to 50 I at the output, eliminating the need for external
matching components. Table 1 lists typical device S
parameters and K f values. Typical noise parameters are
shown in Table 2 .
Shutdown
The MAX2691 includes an optional shutdown feature to
turn off the entire chip. The device is placed in active
mode by default once V CC is applied, due to the on-chip
pullup resistor to V CC at the RFOUT bump (shared with
the 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., 25k I , in order not to load the RF
output signal during active operation.
Applications Information
A properly designed PCB is essential to any RF micro-
wave circuit. Use controlled-impedance lines on all
high-frequency inputs and outputs. Bypass V CC with
decoupling capacitors located close to the device. For
long V CC lines, it may be necessary to add decoupling
capacitors. Locate these additional capacitors further
away from the device package. Proper grounding of
the GND pin is essential. If the PCB uses a topside RF
ground, connect it directly to the GND pin. For a board
where the ground is not on the component layer, connect
the GND pin to the board with multiple vias close to the
package.
