The switch features enhanced AlGaAs anodes which are formed using a patented hetero-junction technology. This technology produces a switch with less loss than conventional GaAs processes. As much as a 0.3 dB reduction in insertion loss can be J1 J2 realized at 50 GHz. 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 for scratch protection. The protective coating prevents damage to the diode junction and anode air-bridges during handling and assembly. Off chip bias circuitry is required. Applications The high electron mobility of AlGaAs and the low capacitance of the PIN diodes makes this switch ideal for fast switching, high frequency, multi-throw Ordering Information switch designs. These AlGaAs PIN switches are use in switching arrays for radar systems, radiometers, Part Number Package test equipment and other multi-assembly components.

MA4AGSW1 SPST Reflective AlGaAs PIN Diode Switch Rev. V6 Operation of the MA4AGSW1 Switch The application of 0 V or a negative DC voltage to either J1 or J2 provides insertion loss for the MA4AGSW1 SPST reflective switch. Isolation is achieved with 10 mA total DC current. The forward bias voltage at the diode bias node is typically 1.4 V for supply currents up to 30 mA and will not exceed 1.6 V. The backside area of the die is the RF and DC return ground plane. The bias network design should yield >30 dB RF to DC isolation. Available for use in conjunction with MACOMs line of AlGaAs switches are two, fully integrated, broadband, monolithic, bias networks which may be used as an alternative to the suggested individual component bias network shown below. Refer to datasheets for the MA4BN1840-1 and MA4BN1840-2 for additional information. The lowest insertion loss, P1dB, IP3, and switching speed is achieved by applying a minimum value of | -2 V | at DC bias node, which is achievable with a standard, ±5 V TTL controlled PIN diode driver.
