PRODUCTION DATA SHEET

DESCRIPTION

This general-purpose amplifier is a Designed as an easily cascadable 50-

low cost, broadband RFIC manu- ohm internally matched gain block, the

factured with an InGaP/GaAs Hetero- LX5501A can be used for IF and RF

junction Bipolar Transistor (HBT) amplification in wireless / wired voice

process (MOCVD).

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.
