GaAs InGaP HBT MMIC

POWER AMPLIFIER, 4.9 - 5.9 GHz

v03.0605

General Description

Features

Functional Diagram

The HMC415LP3 & HMC415LP3E are high effi-

ciency GaAs InGaP Heterojunction Bipolar Tran-

sistor (HBT) MMIC Power amplifiers which operate

between 4.9 and 5.9 GHz. The amplifier is pack-

aged in a low cost, leadless surface mount pack-

age with an exposed base for improved RF and

thermal performance. With a minimum of external

components, the amplifier provides 20 dB of gain,

+26 dBm of saturated power, and 34% PAE from a

+3V supply voltage. Vpd can be used for full power

down or RF output power/current control.

For +15

dBm OFDM output power (64 QAM, 54 Mbps), the

HMC415LP3

&

HMC415LP3E

achieve

an

error

vector magnitude (EVM) of 3.7% meeting 802.11a

linearity requirements.

Gain: 20 dB

34% PAE @ Psat = +26 dBm

3.7% EVM @ Pout = +15 dBm

with 54 Mbps OFDM Signal

Supply Voltage: +3V

Typical Applications

This amplifier is ideal for use as a power

amplifier for 4.9 - 5.9 GHz applications:

• 802.11a WLAN

• HiperLAN WLAN

• Access Points

• UNII & ISM Radios
