Typical Applications
3x3 mm Leadless SMT Package
Functional Diagram
General Description
LE
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.

The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed ground paddle should be connected directly to the ground plane similar to that

should be used to connect the top and bottom
ground planes. The evaluation circuit board shown
is available from Hittite upon request.
