Typical Applications The HMC44ST8 / HMC44ST8E is ideal for applications requiring a high dynamic range amplifi er: GSM, GPRS & EDGE CDMA & W-CDMA CATV/Cable Modem Fixed Wireless & WLL Features Output IP3: +4 to +42 dbm Gain: 12. db @ 2 MHz % PAE @ +28 dbm Pout +17. dbm W-CDMA Channel Power@ -4 dbc ACP Single +V Supply Industry Standard SOT8 Package Included in the HMC-DK2 Designer s Kit Functional Diagram Electrical Specifications, T A = + C, Vs= +V [1] General Description The HMC44ST8 & HMC44ST8E are high dynamic range GaAs InGaP Heterojunction Bipolar Transistor (HBT) ½ watt MMIC amplifi ers operating between.4 and 2. GHz. Packaged in a low cost industry standard SOT8, the amplifi er gain is typically 17.8 db from.8 to 1. GHz and 12. db from 1.8 to 2.2 GHz. Utilizing a minimum number of external components and a single +V supply, the amplifi er output IP3 can be optimized to +4 dbm at. GHz or +42 dbm at 2. GHz. The high output IP3 and PAE makes the HMC44ST8 an ideal driver amplifi er for Cellular/PCS/3G, WLL, ISM and Fixed Wireless applications. Parameter Min. Typ. Max. Min. Typ. Max. Min. Typ. Max.
