MA4AGSW5 SP5T AlGaAs PIN Diode Switch Rev. V5 FEATURES Ultra Broad Bandwidth : 50 MHz to 50 GHz Functional Bandwidth : 50 MHz to 70 GHz 1.7dB Insertion Loss at 50 GHZ 35 dB Isolation at 50 GHz Low Current consumption. -10mA for low loss state +10mA for Isolation state M/A-COM Techs unique AlGaAs hetero-junction anode technology. Silicon Nitride Passivation Polymer Scratch protection RoHS Compliant* and 260C Reflow Compatible Yellow areas indicate bond pads DESCRIPTION The MA4AGSW5 is an Aluminum-Gallium-Arsenide, single pole, five throw (SP4T), PIN diode switch. The switch features enhanced AlGaAs anodes which are formed using M/A-COM Techs patented hetero- junction technology. This technology produces a switch with less loss than conventional GaAs proc- esses. As much as a 0.3 dB reduction in insertion loss can be realized at 50GHz. These devices are fabricated on an OMCVD epitaxial wafer using a process designed for high device uniformity and extremely low parasitics. The diodes themselves exhibit low series resistance, low capacitance, and fast switching speed. They are fully passivated with silicon nitride and have an additional polymer layer Absolute Maximum Ratings T = +25C AMB for scratch protection. The protective coating prevents damage to the diode junction and anode Parameter Maximum Rating air-bridges during handling and assembly. Off chip Operating Temperature -55C to +125C bias circuitry is required. Storage Temperature -55C to +150C APPLICATIONS Incident C.W. RF Power +23dBm C.W. The high electron mobility of AlGaAs and the low Breakdown Voltage 25V capacitance of the PIN diodes makes this switch Bias Current 25mA ideal for fast switching, high frequency, multi-throw switch designs. These AlGaAs PIN switches are use Assembly Temperature +300C < 10 sec in switching arrays for radar systems, radiometers, Junction Temperature +175C test equipment and other multi-assembly compo- nents. Maximum combined operating conditions for RF Power, D.C. bias, and temperature: +23 dBm C.W. 10 mA (per diode) +85C. * Restrictions on Hazardous Substances, European Union Directive 2002/95/EC. 1 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions North America Tel: 800.366.2266 Europe Tel: +353.21.244.6400 is considering for development.
