SPDT
SMT
The HMC132C8 is a surface mount, low
cost, non-hermetic packaged version of the
HMC132G7 MMIC SPDT switch. The device
is a fast, broadband SPDT switch featuring
high (> 42 dB) isolation over the entire band.
The switch is non-reflective at both RF1 and
RF2 ports. Applications for this device
include T/R switching for 5.2 GHz UNII, 5.8
GHz ISM circuits, WLAN, and S,C and X-
Band Telecom radios.
General Description
BANDWIDTH: DC-8 GHz
HIGH ISOLATION : > 50 dB
NON-REFLECTIVE DESIGN

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 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.
