HMC347LP3 / 347LP3E
GaAs MMIC SPDT NON-REFLECTIVE
SWITCH, DC - 14 GHz
v06.0805
General Description
Features
Functional Diagram
The HMC347LP3 & HMC347LP3E are broadband
high isolation non-re ective GaAs MESFET SPDT
switches in low cost leadless QFN surface mount
plastic packages. Covering DC to 14 GHz, the switch
offers high isolation and low insertion loss. The switch
features >50 dB isolation up to 3 GHz and >40 dB
isolation up to 13 GHz. The switch operates using
complementary negative control voltage logic lines of
-5/0V and requires no bias supply. This SPDT is an
excellent alternative to the HMC132C8 SPDT.
High Isolation: >50 dB up to 3 GHz
>45 dB up to 10 GHz
Low Insertion Loss: 1.6 dB @ 10 GHz
Non-Re ective Design
3x3 mm QFN SMT Package
Electrical Speci cations, TA = +25° C, With 0/-5V Control, 50 Ohm System
Typical Applications
The HMC347LP3 / HMC347LP3E is ideal for:
• Basestation Infrastructure
• Fiber Optics & Broadband Telecom
• Microwave Radio & VSAT
• Military Radios, Radar, & ECM
• Test Instrumentation

Pin Descriptions
Suggested Driver Circuit
Pin Number Function Description Interface Schematic
1, 5, 9, 12, 16 N/C This pin should be connected to PCB RF ground to
maximize isolation
2, 4, 6, 8, 13, 15 GND Package bottom has exposed metal paddle that must also
be connected to PCB RF ground.
3, 7, 14 RFC, RF1, RF2 This pin is DC coupled and matched to 50 Ohm. Blocking
capacitors are required if RF line potential is not equal to 0V.

Evaluation PCB
The circuit board used in the nal application
should be generated with proper RF circuit design
techniques. Signal lines at the RF port should have
50 ohm impedance and the package ground leads
and package bottom should be connected directly
to the ground plane similar to that shown above. The
evaluation circuit board shown above is available
from Hittite Microwave Corporation upon request.
