General Description
The HMC393MS8 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
2
UNII radios platforms. The design provides 20 dB of isolation between antennas
and between Tx and Rx ports. The switch
features 1.2 dB insertion loss and high
power handling capability. Switch state is
controlled using four CMOS level control
voltage lines.
Guaranteed Performance Vctl = 0/ +5 Vdc, 50 Ohm System, -40 to +85 deg. C

+23 dBm (VCTL= 0/+5 Vdc).
DC blocking capacitors are required at ports ANT1,
ANT2, Tx, Rx. Choose value for lowest frequency of

The circuit board used in the final 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 sufficient number of VIA holes should be used to connect the top
and bottom ground planes. The evaluation circuit board as shown is available from Hittite upon request.

* R1 & R2 = 100 Ω .
These optional resistors will
provide more RF path to control
circuit isolation.
