The HMC758LP3(E) is a GaAs PHEMT MMIC Low

Noise Amplifier that is ideal for Cellular Infrastructure,

WiMAX & LTE/4G basestation front-end receivers

operating between 700 and 2200 MHz. The amplifier

has been optimized to provide 1.7 dB noise figure,

21 dB gain and +37 dBm output IP3 from a single

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

excellent with minimal external matching and bias

decoupling components. The HMC758LP3(E) 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.

Noise Figure: 1.7 dB

Gain: 22 dB

Output IP3: +37 dBm

Single Supply: +3V to +5V

50 Ohm Matched Input/Output

The HMC758LP3(E) is ideal for:

• Cellular Infrastructure, WiMAX & LTE/4G

• Software Defined Radios

• Repeaters and Femtocells

• Access Points

• Test & Measurement Equipment
