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.
