LX5501B InGAP HBT Gain Block ® TM P RODUCTION D ATA S HEET 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 50ohm 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 5lead SOT-23 package. WWW . Microsemi .C OM KEY FEATURES DESCRIPTION Advanced InGaP HBT DC to 6 GHz Operation Single Supply Low Idle Current (10 - 35 mA) Small Signal Gain ~ 9 dB at 6 GHz P1dB ~ 8 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 • • Input and output matched to 50 ohms for ease of cascading. Cascaded gain blocks can be individually biased for the lowest supply current.
