HMC197 / 197E
v02.0505
GaAs MMIC SOT26 SPDT
SWITCH, DC - 3 GHz
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 5 to 8 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 Vdd = +8V
and A/B set to 0/+8V.
Evaluation Circuit Board
The circuit board used in the final application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF port should have 50
Ohm impedance and the package ground leads and
package bottom should be connected directly to the
ground plane similar to that shown above. The eval-
uation circuit board shown above is available from
Hittite Microwave Corporation upon request.
