Typical Applications
This switch is ideal for use as a DPDT Diversity or
SP3T Switch for:
HiperLAN & 802.11a WLAN
WiMAX & Fixed Wireless
UNII Radios
Mulit-beam Antenna Switching
The HMC436MS8G & HMC436MS8GE are low cost
C-band DPDT switches that operate between 4.9
and 5.9 GHz. This switch can operate as an inte-
grated antenna diversity and transmit/receive switch
for the 802.11a/HiperLAN and UNII radio platforms.
The switch can also operate as a SP3T switch with
any of the RF ports serving as the common port. The
design provides 20 dB of isolation between antennas
and between Tx and Rx ports. The switch features
1 dB insertion loss and high power handling capabil-
ity. Switch state is controlled using four control vol-
tage lines toggled between 0 and +3 to +5V.
