LX5551
® 2.4-2.5 GHz Front-End Module with Internally
Matched Power Amplifier & SPDT for 11b/g/n
PRODUCTION DATA SHEET
DESCRIPTION
LX5551 is a high-performance The Rx path of LX5551 includes a
WLAN front-end module (FEM) for low-cost SPDT switch with excellent
802.11b/g/n and other applications in insertion loss and isolation. It features a
the 2.4-2.5GHz frequency range. very low Tx-to-Rx port leakage in
LX5551 integrates an advanced receive mode.
InGaP/GaAs Heterojunction Bipolar LX5551 is available in a 16-pin,
Transistor (HBT) power amplifier with 3x3mm micro-lead package (MLPQ-
both input/output impedance matching, 16L). With its best-class performance
and an InGaAs pseudomorphic HEMT and compact footprint, LX5551 offers an
(pHEMT) switch, into a single 3x3mm ideal front-end solution for the ever
package.
demanding design requirements of
The Tx path of LX5551 features a today’s WLAN systems, including
two-stage monolithic microwave 802.11b/g and the latest 11n MIMO
integrated circuit (MMIC) power implementation.
amplifier with active bias circuitry, and
50 Ω input/output matching inside the
package. With 3.3V supply voltage and
90mA nominal bias current, the Tx
path provides 27dB gain and +18dBm
linear output power, with extremely low
total EVM (<3%) for 64QAM/54Mbps
OFDM. Both gain and power are
readily measured at antenna port, with
switch insertion loss included.
