FEATURES
NEC's 1.5W
GaAs MMIC POWER AMPLIFIER
DESCRIPTION
UPG2118K
NEC's UPG2118K is a 1.5W, 3 stage power amplifier
developed primarily for DCS/PCS1800 applications.
With modified external matching the UPG2118K can
be tuned from 800 to 2500 MHz.
Use of E-mode FET technology delivers high efficiency
and high linearity with a single positive low voltage
supply.
APPLICATIONS
• 1800 MHz DCS/PCS
• 915 AND 2450 ISM BAND USAGE
• AUTOMATIC METER READERS
• WIRELESS SECURITY
• SATELLITE UPLINK
