The MASW-007935 is ideally suited for applications where very low power consumption, low insertion loss and very small size are required. Typical application is in dual band systems which require switching between small signal components such as filter banks, single band LNA's, converters etc. The MASW-007935 can be used in applications up to 0.25 Watts in systems such as CDMA, W-CDMA, PCS, DCS1800, GSM and other analog/ digital wireless communications systems. Pin 1 C = 39 pF CGND C = 39 pF Functional Schematic Negative Control Voltage V1 RFC V2 RF1 GND RF2 The MASW-007935 is fabricated using a mature 0.5 micron GaAs PHEMT process. The process features full passivation for increased performance and reliability.

External DC blocking capacitors are required on all RF ports when using positive voltage control. 3. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 1 GHz, 39 pF for 0.5 GHz - 3 GHz.

External DC blocking capacitors are required on all RF ports and GND. GND capacitors can be used with positive control voltage to resonate lead inductance for improved isolation. 7. If negative control is used, DC blocking capacitors and GND capacitors are not required. Handling Procedures 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. 2 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
