| RoHS Compliant SPDT High Isolation Terminated Switch 0.01 - 3.0 GHz Features * Positive Voltage Control: 0 / +5 V * High Isolation: 55 dB @ 0.9 GHz 50 dB @ 1.9 GHz * 50 Internal Terminations * Low Insertion Loss: 0.6 dB @ 0.9 GHz 0.7 dB @ 1.9 GHz * Lead-Free MSOP-8-EP Package * 100% Matte Tin Plating over Copper * Halogen-Free "Green" Mold Compound * 260C Reflow Compatible * RoHS* Compliant Version of MASWSS0024 MASWSS0178 V3 Functional Block Diagram Description The M/A-COM MASWSS0178 GaAs monolithic switch provides high isolation in a lead-free, plastic surface mount package. The MASWSS0178 is ideal for applications across a broad range of frequencies including synthesizer switching, transmit / receive switching, switch matrices and filter banks in systems such as radio and cellular equipment, PCS, GPS, and fiber optic modules. M/A-COM fabricates the MASWSS0178 using a 1.0-micron gate length MESFET process. The process features full chip passivation for performance and reliability.

External DC blocking capacitors are required on all RF ports (47 pF capacitors are recommended). Use larger value capacitors for lower frequency operation (e.g. use 10,000 pF capacitors to optimize insertion and return loss at frequencies below 50 MHz). 6. Terminated return loss is governed by blocking capacitors internal to the device; see applications plot.
