DESCRI PTI O N

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.
