= +25 C, Vctl = 0/+5 Vdc, 50 Ohm System
Typical Applications
This switch is ideal for use as a DPDT Diversity
Switch for 5.0 - 6.0 GHz applications:
HiperLAN
UNII
The HMC393MS8G is a low cost C-band DPDT
switch that operates between 5.0 and 6.0 GHz.
This switch can operate as an integrated antenna
diversity and transmit/receive switch for the
HyperLAN and UNII radio platforms. The design
provides 20 dB of isolation between antennas
and between Tx and Rx ports. The switch fea-
tures 1.2 dB insertion loss and high power han-
dling capability. Switch state is controlled using
four CMOS level control voltage lines.

Evaluation PCB
The circuit board used in the fi nal application should use RF
circuit design techniques. Signal lines should have 50 ohm
impedance while the package ground leads and exposed
paddle should be connected directly to the ground plane
similar to that shown above. A suffi cient number of VIA
holes should be used to connect the top and bottom ground
planes. The evaluation circuit board shown above is avail-
able from Hittite upon request.
List of Material
*R1 & R2 = 100 Ohm.
These optional resistors will
provide more RF path to control
circuit isolation.
