LMX2119 1.9 GHz Power Amplifier
General Description
The LMX2119 1.9 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
technology that allows single supply (
a
3V) operation.
The LMX2119 consists of two MESFETs cascaded to pro-
vide 24.5 dB of power gain. The output power at 3.6V is
a
26.5 dBm with an input power level of
a
2 dBm. The input
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.
