Functional Diagram
General Description
The HMC491LP3 is a versatile, integrated, Low
Noise Amplifier (LNA) featuring a bypass mode
intended for 3.4 to 3.8 GHz Fixed Wireless &
WLL applications. The amplifier provides 16 dB
of gain, 2 dB noise figure and +3 dBm input IP3
while requiring only 9 mA from a +3V supply.
Using a single control line, the LNA can be
switched into a low loss 2.2 dB bypass mode
reducing the current consumption to 20 µA. A
low cost, leadless 3x3 mm QFN surface mount
package (LP3) houses the amplifier. No external
RF matching components are required.

The circuit board used in the final application should
use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground
leads and exposed paddle should be connected directly
to the ground plane similar to that shown. A sufficient
number of VIA holes should be used to connect the top
and bottom ground planes. The evaluation circuit board
shown is available from Hittite upon request.
