The HmC618lp3e is a GaAs pHemT mmiC

low Noise Amplifier that is ideal for Cellular/3G and

lTe/wimAX/4G

basestation

front-end

receivers

operating between 1.2 - 2.2 GHz. The amplifier has

been optimized to provide 0.75 dB noise figure,

19 dB gain and +36 dBm output ip3 from a single

supply of +5V. input and output return losses are

excellent and the lNA requires minimal external

matching and bias decoupling components. The

HmC618lp3e shares the same package and pinout

with the HmC617lp3e 0.55 - 1.2 GHz lNA. The

HmC618lp3e can be biased with +3V to +5V and

features an externally adjustable supply current

which allows the designer to tailor the linearity

performance of the lNA for each application. The

HmC618lp3(e) offers improved noise figure versus

the previously released HmC375lp3(e) and the

HmC382lp3(e).

The HmC618lp3e is ideal for:

• Cellular/3G and lTe/wimAX/4G

• BTs & infrastructure

• repeaters and femto Cells

• public safety radios
