General Description
8
The HMC-C019 is a high speed, high isolation GaAs
MESFET SPST switch housed in a miniature hermetic
module with field replaceable SMA connectors.
Covering DC to 20 GHz, the switch features 100 dB
isolation up to 4 GHz and 65 dB isolation up to 20
GHz. CMOS interface allows a positive +5V bias
voltage at very low DC currents. This non-reflective
switch exhibits very fast switching speeds, with very
low switching transients making it ideal for high speed
RF pulse modulation applications.
