HMC336MS8G
GaAs MMIC SPDT NON-REFLECTIVE
POSITIVE CONTROL SWITCH, DC* - 6.0 GHz
v01.1202
General Description
Features
Functional Diagram
The HMC336MS8G is a broadband non-refl ec-
tive GaAs MESFET SPDT switch in a low cost
8 lead MSOP8G surface mount package with an
exposed ground paddle. Covering DC to 6.0 GHz,
this switch offers high isolation and low insertion
loss. The switch operates using a positive control
voltage of 0/+5 Volts, and requires a fi xed bias of
+5V. This switch is suitable for usage in 50-Ohm
or 75-Ohm systems.
Broadband Performance: DC - 6.0 GHz
High Isolation: 42 dB@ 6 GHz
Low Insertion Loss: 1.6 dB@ 6 GHz

Evaluation PCB
The circuit board used in the fi nal application should
be generated with proper RF circuit design techniques.
Signal lines at the RF port should have 50 ohm imped-
ance and the package ground leads and backside
ground slug should be connected directly to the ground
plane similar to that shown above. The evaluation circuit
board shown above is available from Hittite Microwave
Corporation upon request.
