SW-439 GaAs High Isolation Switch DC - 3.0 GHz Rev. V4 Functional Schematic 4 Features • • • • • Low Power Consumption: < 15 µA @ +2.5V High Isolation: 50 dB Typical @ 2 GHz Low Insertion Loss: 0.7 dB @ 2 GHz Positive 2.5 to 5 V Control Low Cost Plastic MSOP-10 Package C = 39 pF C = 39 pF Pin 10 Description The SW-439 is a GaAs MMIC SPDT switch in a low cost MSOP-10 surface mount plastic package. This part is ideal for high isolation, broadband switching requirements. Typical applications include synthesizer switching, transmit/ receive switching, switch matrices and filter banks in systems such as radio and cellular equipment, PCM, GPS, and fiber optic modules. Pin 1 C = 39 pF The SW-439 is fabricated as a monolithic GaAs MMIC using a 0.5 micron pHEMT process. The process features full passivation. Ordering Information1 4. For improved performance at frequencies below 500 MHz, use larger value capacitors.
