3x3 mm Leadless SMT Package

Functional Diagram

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 3.0 GHz. Evaluation boards are available

with or without a GPS L1 (1575 MHz) band pass ﬁlter.
