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
amplier 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 lter between the
two amplier stages. This ltering approach enables
the receiver to reject nearby blocking signals such
as those emitted from cellular and 3G hand-helds,
without incurring the noise gure degradation
associated with a high rejection pre-lter. When
combined with the appropriate interstage bandpass
lter, this LNA can be used as a receiver pre-amplier
in various applications from 1.2 to 3 GHz. Evaluation
boards are available with or without a GPS L1
(1575 MHz) band pass lter.
