Functional Diagram
General Description
the hMc547ALc3 is a general purpose broadband
high isolation non-reflective 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.
