AMPLIFIERS - LOW NOISE - SMT

HMC548LP3 / 548LP3E
v03.1011
SiGe HBT MMIC LOW NOISE
AMPLIFIER, 1.2 - 3.0 GHz
General Description
Features
Functional Diagram
Single Supply: Vcc = +3 to +5V
Low Noise Figure: 1.3 dB
High Output IP3: +21 dBm
No External Matching Required
External Filter Access
3x3 mm Leadless SMT Package
Electrical Specications, TA = +25°C*
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
amplier 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 amplier 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-amplier
in various applications from 1.2 to 3 GHz. Evaluation
boards are available with or without a GPS L1
(1575 MHz) band pass lter.
