Tiny Low-Noise Amplifiers for HSPA/LTE
Detailed Description
The MAX2666/MAX2668 are low-power LNAs designed
for 3G mobile applications. The devices feature low
noise, high linearity, and three gain steps in a tiny plastic
package.
Input and Output Matching
The devices require one matching inductor at the input
port in series with a DC-blocking capacitor to achieve
optimal performance in NF, gain, IIP3, and phase shift.
Table 1 presents the recommended input-matching
network values. The output port is internally matched to
50 I , eliminating the need for external matching com-
ponents. At the output port, an external DC-blocking
capacitor should be used to isolate the control function
of the output pin.
DC Decoupling and Layout
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 a
decoupling capacitor located close to the device.
For long V CC lines, it might be necessary to add decou-
pling capacitors. Locate these additional capacitors
further away from the device package. Proper grounding
of the GND pins is essential. If the PCB uses a top-side
RF ground, connect it directly to the GND pins. For a
board where the ground is not on the component layer,
connect the GND pins to the board with multiple vias
close to the package.
Gain Control
The devices’ LNA_OUT/GAIN0 pin is also used as a
control pin for the LNA gain modes according to the gain
control table. GAIN0 logic level is set through an external
20k I resistor. An external DC-blocking capacitor should
be used to isolate the control function of this dual-pur-
pose pin (see the Typical Operating Circuit ). The GAIN1
pin must be set to either logic-high or logic-low.
