Typical Applications
The HMC241LP3 / HMC241LP3E is ideal for:
Base Stations & Repeaters
WLAN, WiMAX & WiBro
CATV / DBS
Test Equipment
The HMC241LP3 & HMC241LP3E are general pur-
pose non-refl ective SP4T switches in low cost lead-
less surface mount packages. Covering DC - 4.0
GHz, this switch offers high isolation and has a low
insertion loss of 0.7 dB at 2 GHz. The switch offers a
single positive bias and true TTL/CMOS compatibil-
ity. A 2:4 decoder is integrated on the switch requiring
only 2 control lines and a positive bias to select each
path, replacing 4 to 8 control lines normally required
by GaAs SP4T switches.

SWITCH, DC - 4.0 GHz
v01.0905
HMC241LP3
/
241LP3E
The circuit board used in the fi nal application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF port should have 50
ohm impedance and the package ground leads and
package bottom should be connected directly to the
ground plane similar to that shown above. The evalua-
tion circuit board shown above is available from Hittite
Microwave Corporation upon request.
