The LX5501B is a low cost, broadband RFIC amplifier that has been manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) process (MOCVD). Designed as an easily cascadable 50-ohm internally matched gain block, the LX5501B can be used for IF and RF amplification in wireless / wired voice and data communication products and broadband test equipment operating up to 6 GHz.

The amplifier is available in a plastic 5-lead SOT-23 package.
