HMC669LP3 / 669LP3E
GaAs PHEMT MMIC LNA w/
FAILSAFE BYPASS MODE, 1700 - 2200 MHz
v04.0709
General Description
Features
Functional Diagram
The HmC669lp3(e) is a versatile, high dynamic range
GaAs mmiC low Noise Amplifier that integrates a
low loss lNA bypass mode on the iC. The amplifier
is ideal for receivers and lNA modules operating be-
tween 1.7 and 2.2 GHz and provides 1.4 dB noise
figure, 17 dB of gain and +29 dBm ip3 from a single
supply of +5V @ 86mA. input and output return losses
are excellent and no external matching components
are required. A single control line is used to switch
between lNA mode and a low loss bypass mode.
failsafe topology also enables the lNA bidirectional
bypass path when no DC power is available.
Noise figure: 1.4 dB
output ip3: +29 dBm
Gain: 17 dB
failsafe operation:
Bypass is enabled when lNA is unpowered
single supply: +3V or +5V
16 lead 3x3mm QfN package: 9 mm2
Electrical Specifications, T
A = +25° C, Rbias = 15 Ohm
Typical Applications
The HmC669lp3(e) is ideal for:
Cellular/3G and lTe/wimAX/4G
BTs & infrastructure
repeaters and femtocells
Tower mounted Amplifiers
Test & measurement equipment
