HMC232ALP4E
v00.0613
GaAs MMIC SPDT NON-REFLECTIVE
SWITCH, DC - 12 GHz
General Description
Features
Functional Diagram
The HMC232ALP4E is a broadband high isolation
non-reective GaAs MESFET SPDT switch in a low
cost leadless QFN surface mount plastic package.
Covering DC to 12 GHz, the switch features >57dB
isolation up to 3 GHz and >45 dB isolation up to
12 GHz. Input P1dB compression is +30 dBm typ-
ical, while input IP3 is +48 dBm. The switch operates
using complementary negative control voltage logic
lines of -5/0V and requires no bias supply.
Isolation: 57 dB @ 3 GHz
50 dB @ 6 GHz
Input P1dB: +30 dBm
Insertion Loss: 1.5 dB Typical @ 6 GHz
Non-Reective Design
24 Lead 4x4mm QFN Package: 16mm²
Included in the HMC-DK005 Designer’s Kit
Electrical Specications, TA = +25° C, With 0/-5V Control, 50 Ohm System
Typical Applications
The HMC232ALP4E is ideal for:
• Telecom Infrastructure
• Microwave Radio & VSAT
• Military Radios, Radar & ECM

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.
