DESCRIPTION
This general-purpose amplifier is a
low cost, broadband RFIC manu-
factured with an InGaP/GaAs Hetero-
junction Bipolar Transistor (HBT)
process (MOCVD).
Designed as an easily cascadable 50-
ohm internally matched gain block, the
LX5501A can be used for IF and RF
amplification in wireless / wired voice
and data communication products as
well as in broadband test equipment
operating up to 6 GHz.
The amplifier is available in a plastic
5-lead SOT-23 package.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
KEY FEATURES
Advanced InGaP HBT
DC to 6 GHz Operation
Single Supply
Low Idle Current (10 - 35 mA)
Small Signal Gain ~ 11 dB at 6
GHz
P1dB ~ 11 dBm at 6 GHz
SOT-23 Package
APPLICATIONS
PA driver for WLAN and
Cordless Phones.
VCO buffer.
Low Current, High Gain
Cascaded Amplifiers.
PRODUCT HIGHLIGHT
Fully characterized for 5v operation (with external
bias resistor).
Input and output matched to 50 ohms for ease of
cascading.
Cascaded gain blocks can be individually biased
for the lowest supply current.
