HMC241ALP3E
v00.0513
GaAs MMIC SP4T NON-REFLECTIVE
SWITCH, DC - 4 GHz
General Description
Features
Functional Diagram
High Isolation: 43 dB @ 2 GHz
Low Insertion Loss: 0.7 dB @ 2 GHz
Single Positive Supply: Vdd = +5V
Integrated 2:4 TTL Decoder
16 Lead 3x3mm SMT Package: 9m
Electrical Specications, TA = +25° C, For TTL Control and Vdd = +5V in a 50 Ohm System
Typical Applications
The HMC241ALP3E is ideal for:
• Base Stations & Repeaters
• WLAN, WiMAX & WiBro
• CATV / DBS
• Test Equipment
The HMC241ALP3E is a general purpose non-
reective SP4T switch in a low cost leadless sur-
face mount package. Covering DC - 4 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 compatibility. 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.

Evaluation PCB
The circuit board used in the 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
evaluation circuit board shown above is available
from Hittite Microwave Corporation upon request.
