Description

M/A-COM’s MASWSS0148 is a GaAs monolithic
single pole single throw (SPST) terminated switch in
a lead-free 3 mm 12-lead PQFN plastic package.
The MASWSS0148 is ideally suited for use where
low power consumption, small size and high isolation are required.
Typical applications include PCS and GSM LO
switching, switch matrices and switched filter banks
in systems such as radio and cellular equipment.
The MASWSS0148 is fabricated using a mature 1micron gate length GaAs MESFET process. The
process features full chip passivation for increased
performance and reliability.

6. For positive voltage control, external DC blocking capacitors are required on all RF ports.
7. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 300 MHz - 1 GHz, 39 pF for 0.5 GHz - 4 GHz.

8. Differential voltage, V(state 1) - V(state 0), must be
+2.5 V minimum and must not exceed 8.5 V.
9. 0 = 0 V ± 0.2 V, 1 = VDD = 2.5 V to 8.5 V
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide 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.
