General Description
Features
Functional Diagram
The HMC547ALC3 is a general purpose broadband
high isolation non-reective GaAs pHEMT 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
military 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
39 dB @ 20 GHz
Low Insertion Loss: 1.9 dB @ 10 GHz
2.2 dB @ 20 GHz
Fast Switching: 6 ns
