Typical Applications
The HMC548LP3 / HMC548LP3E is ideal for:
• Automotive Telematics
• GPS Antenna Modules / Boosters
• Location Based Portables
• Satellite Navigation
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 3.0 GHz. Evaluation boards are available
with or without a GPS L1 (1575 MHz) band pass filter.
