HMC194MS8 / 194MS8E
GaAs MMIC SPDT SWITCH
DC - 3 GHz
v06.0608
General Description
Features
Functional Diagram
Ultra Small Package: MSOP8
High Isolation: 50 dB
Positive Control: 0/+3V to 0/+7V
Electrical Speci cations, TA = +25° C, Vctl = 0/+5 Vdc, 50 Ohm System
Typical Applications
The HMC194MS8 /HMC194MS8E is ideal for:
• Cellular/PCS Base Stations
• Portable Wireless
• MMDS & WirelessLAN
The HMC194MS8 & HMC194MS8E are low-cost
SPDT switches in 8-lead MSOP packages for use in
applications which require high isolation between two
RF paths. The devices can control signals from DC to
3 GHz and have been optimized to provide extremely
high isolation with minimal insertion loss in medium
and low power applications. On chip circuitry allows
positive voltage control operation at very low DC cur-
rents with control inputs compatible with CMOS and
most TTL logic families. RF1 and RF2 are re ective
opens when “OFF”.

Typical Application Circuit
Notes:
1. Set logic gate and switch Vdd = +3V to +5V and use HCT series logic to provide a TTL driver interface.
2. Control inputs A/B can be driven directly with CMOS logic (HC) with Vdd of 3 to 7 Volts applied to the CMOS logic gates.
3. DC Blocking capacitors are required for each RF port as shown. Capacitor value determines lowest frequency of operation.
4. Highest RF signal power capability is achieved with Control set to 0/+7V.

Evaluation Circuit Board
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.
