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.
