HMC548LP3

HMC548LP3 / 548LP3E v03.1011 SiGe HBT MMIC LOW NOISE AMPLIFIER, 1.2 - 3.0 GHz Amplifiers - Low Noise - SMT Typical Applications Features The HMC548LP3 / HMC548LP3E is ideal for: Single Supply: Vcc = +3 to +5V Automotive Telematics Low Noise Figure: 1.3 dB GPS Antenna Modules / Boosters High Output IP3: +21 dBm Location Based Portables No External Matching Required Satellite Navigation OLETE Functional Diagram External Filter Access 3x3 mm Leadless SMT Package General Description The HMC548LP3 & HMC548LP3E 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 HMC548LP3 & HMC548LP3E 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. BS Electrical Specifications, TA = +25°C* Parameter Min. Typ. Max. Min. Typ. Max.
