HMC548LP3 / 548LP3E v03.1011 SiGe HBT MMIC LOW NOISE AMPLIFIER, 1.2 - 3.0 GHz Typical Applications Features The HmC548lp 3 / HmC548lp 3e is ideal for: s ingle s upply: Vcc = +3 to +5V Automotive Telematics l ow Noise f igure: 1.3 dB GPS Antenna Modules / Boosters High o utput ip3: +21 dBm Location Based Portables No external matching r equired Satellite Navigation external f ilter Access 3x3 mm l eadless s mT package Functional Diagram General Description The HmC548lp 3 & HmC548lp 3e are comprised of two internally matched SiGe HBT MMIC low noise amplifier stages housed in 3x3 mm leadless smT packages. The unique topology of the HmC548lp 3 & HmC548lp 3e provides interstage access allowing the designer to place a bandpass filter between the two amplifier stages. This filtering approach enables the receiver to reject nearby blocking signals such as those emitted from cellular and 3G hand-helds, without incurring the noise figure degradation associated with a high rejection pre-filter. when combined with the appropriate interstage bandpass filter, this LNA can be used as a receiver pre-amplifier in various applications from 1.2 to 3 GHz. Evaluation boards are available with or without a GPS L1 (1575 MHz) band pass filter. Electrical Specifications, T = +25C* A parameter min. Typ. max. min. Typ. max.
