HMC547LP3 / 547LP3E
v02.0612
GaAs MMIC SPDT NON-REFLECTIVE
SWITCH, DC - 20 GHz
General Description
Features
Functional Diagram
The HMC547LP3 & HMC547LP3E are general pur-
pose broadband high isolation non-reective GaAs
MESFET SPDT switches in low cost leadless QFN
surface mount plastic packages. Covering DC to
20 GHz, the switch offers high isolation and low
insertion loss. The switch features >50 dB isolation
up to 5 GHz and >45 dB isolation up to 15 GHz.
The switch operates using complementary negative
con-trol voltage logic lines of -5/0V and requires no
bias supply. The HMC547LP3 & HMC547LP3E are
packaged in leadless QFN 3x3 mm surface mount
packages.
High Isolation: >50 dB up to 5 GHz
>45 dB up to 15 GHz
Low Insertion Loss: 1.6 dB @ 10 GHz
2 dB @ 20 GHz

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.
