GaAs InGaP HBT 1 WATT

POWER AMPLIFIER, 3.3 - 3.8 GHz

v03.0710

General Description

Features

Functional Diagram

The HmC409lp4 & HmC409lp4e are high efficiency

GaAs inGap HBT mmiC power amplifiers operating

from 3.3 to 3.8 GHz. The amplifier is packaged in a

low cost, leadless smT package. Utilizing a minimum

of external components the amplifier provides 31 dB

of gain and +32.5 dBm of saturated power from a

+5V supply voltage. The power control (Vpd) can be

used for full power down or rf output power/current

control. for +22 dBm ofDm output power (64 QAm,

54 mbps), the HmC409lp4 & HmC409lp4e achieve

an error vector magnitude (eVm) of 2%, meeting

wimAX 802.16 linearity requirements.

Gain: 31 dB
