HMC347ALP3E
GaAs MMIC SPDT NON-REFLECTIVE
SWITCH, DC - 14 GHz
v02.0217
General Description
Features
Functional Diagram
The HMC347ALP3E is a broadband
high isolation non-reective GaAs pHEMT SPDT
switch in low cost leadless QFN surface mount plastic
package. Covering DC to 14 GHz, the switch offers
high isolation and low insertion loss. The switch fea-
tures >54 dB isolation up to 3 GHz and >44 dB isolation
up to 13 GHz. The switch operates using complemen-
tary negative control voltage logic lines of -5/0V and
requires no bias supply.
High Isolation: >54 dB up to 3 GHz
>44 dB up to 10 GHz
Low Insertion Loss: 1.8 dB @ 10 GHz
Non-Reective Design
3x3 mm QFN SMT Package
