SWITCHES - SPST - SMT
14 - 1
GaAs MMIC SPST
FAILSAFE SWITCH, DC - 6 GHz
General Description
Features
Functional Diagram
Failsafe Operation - “On” When Unpowered
Wide Vdd Range: 1.2V to 5V
Very Low On State Current: 200 nA
Low Insertion Loss: 0.7 dB
High IP3: +52 dBm
Compact SOT26 SMT Package
Electrical Specications
TA = +25° C, Vdd = +3.3 Vdc, Vctl = 0/+3.3 Vdc (Unless Otherwise Stated), 50 Ohm System
Typical Applications
The HMC550 / HMC550E is ideal for:
• RFID & Electronic Toll Collection (ETC)
• Tags, Handsets & Portables
• ISM, WLAN, WiMAX & WiBro
• Automotive Telematics
• Test Equipment
The HMC550 and HMC550E are low-cost SPST
Failsafe switches in 6-lead SOT26 plastic packages
for use in switching applications which require low
insertion loss and very low current consumption.
With 0.7 dB typical loss, these devices can control
signals from DC to 6 GHz and are especially suited
for IF and RF applications including RFID, ISM,
automotive and battery powered tags and portables.
RF1 and RF2 are reective opens when “Off”. The
switch requires a minimal amount of DC current in the
“On” state, and offers compatibility with CMOS and
some TTL logic families. The failsafe topology results
in the switch being normally “On”, i.e. low insertion
loss from RF1 to RF2, when no DC bias is applied.

Evaluation PCB
The circuit board used in the nal application
should be generated with proper RF circuit design
techniques. Signal lines at the RF port should
have 50 Ohm impedance and the package ground
leads should be connected directly to the ground
plane similar to that shown above. The evalua-
tion circuit board shown above is available from
Hittite Microwave Corporation upon request.
