SWITCHES - SMT
The HMC547LP3 is a general purpose broadband
high isolation non-reflective GaAs MESFET
SPDT switch in a low cost leadless QFN surface
mount plastic package. 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
control voltage logic lines of -5/0V and requires
no bias supply. The HMC547LP3 is packaged
in a leadless QFN 3 x 3 mm surface mount
package.
