HMC-C019
HIGH ISOLATION SPST SWITCH
MODULE, DC - 20 GHz
v02.1007
General Description
Features
Functional Diagram The HMC-C019 is a high speed, high isolation GaAs
MESFET SPST switch housed in a miniature hermetic
module with  eld 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-re ective
switch exhibits very fast switching speeds, with very
low switching transients making it ideal for high speed
RF pulse modulation applications.
High Isolation: 100 dB up to 4 GHz
65 dB up to 20 GHz
Low Insertion Loss: 3.5 dB @ 10 GHz
4.0 dB @ 16 GHz
Fast Switching RF Pulse Modulator
Non-Re ective Topology
Hermetically Sealed Module
Field Replaceable SMA connectors
-55 to +85 °C Operating Temperature
Electrical Speci cations
TA = +25° C, With Vdc1, Vdc2 = +5V & 0/+5V Control, 50 Ohm System
Typical Applications
The HMC-C019 is ideal for:
• Basestation Infrastructure
• Fiber Optics & Broadband Telecom
• Microwave Radio & VSAT
• Military Radios, Radar, & ECM
• Test Instrumentation
