switch-limiter with integrated bias networks. This
surface mount, small configuration is designed with
minimal parasitics usually associated with hybrid
MIC designs incorporating beam lead and/or
bondable PIN diodes that require chip and wire
assembly. This standard HQFN enables reliable,
repeatable high volume manufacturing with
MACOMs’ design techniques to maximize heat
dissipation in a plastic package.
This SP2T switch-limiter is designed to optimize Ant
to R
X
loss and handle +51 dBm CW through the
T
X
path to an external high power 50 Ω termination.
This device incorporates a high power SP2T switch,
a limiter function, and a fully integrated RF & DC
bias network.
The MASL-011023 is designed to be used in 2.7 -
3.5 GHz higher power switch applications that
require high volume, surface mount, solder reflow
manufacturing. It is RoHS compliant, durable,
reliable and capable of meeting all military,
commercial, and industrial environments.

3. Exceeding any one or combination of these limits may cause

switching diode. ―Rcom‖ is 220 Ω. G1 is connected to
ground externally. See Application Circuit Diagram.
Bias Control
Handling Procedures
Please observe the following precautions to avoid
damage:
Optimal operation is achieved by simultaneous
application of positive DC voltage to the low loss
switching arm and negative DC voltage to the
isolating switching arm.
In the low loss state, the diode is forward biased with
current. In the isolated state, the series diode is
reverse biased with voltage.
Minimum Reverse Bias Required (T
X
mode):
30 V DC Voltage for 125 W CW Power
R. Caverly and G. Hiller, ―Establishing the Minimum Reverse
Bias for a P-I-N Diode in a High Power Switch,‖ IEEE Transac-
tions on Microwave Theory and Techniques, Vol.38, No.12,

Static Sensitivity
RF Integrated Circuits are sensitive to electrostatic
discharge (ESD) and can be damaged by static
electricity. Proper ESD control techniques should
be used when handling these devices.
