DESCRIPTION
LX5552 is a high-integration, high- +17dBm linear output power, with low
performance WLAN front-end module total EVM (<3%) for 64QAM/ 54Mbps
(FEM) for 802.11b/g/n and other OFDM. Both gain and power are
applications in the 2.4-2.5GHz readily measured at antenna port with
frequency range. LX5552 integrates a the insertion loss of the Tx switch
fully matched InGaP/GaAs Hetero- included.
junction Bipolar Transistor (HBT) The Rx path of LX5552 features
power amplifier, a low noise amplifier small-signal gain of 12.5dB, low noise
based on InGaAs Enhancement mode figure of 2dB, and high input third-
pseudo-morphic high electron order intercept point (IIP3) of +5dBm
mobility transistor (E-pHEMT) with the insertion loss of the the Rx
technology, and a low-cost Depletion switch loss included. The LNA
mode pHEMT (D-pHEMT) single consumes about 10mA current with
pole double throw (SPDT) antenna 3.3V supply voltage.
switch in a single package.
LX5552 is available in a 16-pin,
The Tx path of LX5552 features a 3x3mm micro-lead package (MLPQ-
two-stage monolithic microwave 16L). With its high level of functional
integrated circuit (MMIC) power integration, best-class performance,
amplifier with active bias circuitry, compact footprint and low profile,
on-chip output power detector, and LX5552 offers an ideal front-end
50Ω input/output matching inside the solution for the ever demanding design
package. With 3.3V supply voltage requirements of today’s WLAN
and 80mA bias current, the Tx path systems, including 802.11b/g and the
provides about 26dB power gain and latest 11n MIMO applications.
