LMX2119 19 GHz Power Amplifier

General Description

The LMX2119 19 GHz Power Amplifier is a monolithic inte-

grated power amplifier suitable for use in the Digital Europe-

an Cordless Telecommunications (DECT) system as well as

other mobile telephony and wireless communications appli-

cations It is fabricated using an advanced Gallium Arsenide

The LMX2119 consists of two MESFETs cascaded to pro-

vide 245 dB of power gain The output power at 36V is

a

VSWR of the power amplifier remains constant in the ON

and OFF state

The LMX2119 is available in a 16-pin SOIC surface mount

plastic package
