HMC547LC3
v01.0514
GaAs MMIC SPDT NON-REFLECTIVE
SWITCH, DC - 28.0 GHz
General Description
Features
Functional Diagram
The HMC547LC3 is a general purpose broadband high
isolation non-reective GaAs MESFET SPDT switch
in a ceramic 3x3 mm leadless surface mount package.
Covering DC to 28.0 GHz, the switch offers over 40 dB
isolation and less than 2 dB insertion loss at midband.
The wide bandwidth, fast switching, and compact size
make this absorbtive SPDT ideal for miliitary EW/ECM
and test equipment applications. The switch operates
using complementary negative control voltage logic
lines of -5/0V and requires no bias supply.
High Isolation: 45 dB @ 10 GHz
40 dB @ 20 GHz
Low Insertion Loss: 1.6 dB @ 10 GHz
1.9 dB @ 20 GHz
Fast Switching: 6 ns
Non-Reective Design
16 Lead Ceramic 3x3 mm SMT Package: 9mm2
Electrical Specications, TA = +25° C, With 0/-5V Control, 50 Ohm System
Typical Applications
The HMC547LC3 is ideal for:
• Fiber Optics & Broadband Telecom
• Microwave Radio & VSAT
• Military Radios, Radar, & ECM
• Test Instrumentation

Evaluation PCB
The circuit board used in the 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.
