MASW-002103-1363 Silicon SPDT Surface Mount HMIC PIN Diode Switch 50 MHz - 20 GHz Rev. V11 Features Usable up to 26 GHz Low Insertion Loss High Isolation Low Parasitic Capacitance and Inductance RoHS Compliant Surmount Package Rugged, Fully Monolithic Glass Encapsulated Construction Up to +38 dBm CW Power Handling @ +25°C Silicon Nitride Passivation Polymer Scratch Protection Solderable Description Functional Schematic The MASW-002103-1363 is a SPDT, surmount, broadband, monolithic switch using two sets of series and shunt connected PIN diodes. This device is designed for use in broadband, low to moderate signal, high performance, switch applications up to 20 GHz. It is a surface mountable switch configured for optimized performance and offers a distinct advantage over MMIC, beamlead and chip and wire hybrid designs. Because the PIN diodes of the MASW-002103-1363 are integrated into the chip and kept within close proximity, the parasitics typically associated with other designs that use individual components are kept to a minimum. To minimize the parasitics and achieve high performance the MASW-002103-1363 is fabricated using MACOM’s HMIC (Heterolithic Microwave Integrated Circuit) process. This process allows the silicon pedestals, which form the series and shunt diodes or vias, to be imbeded in low loss, low dispersion glass. The combination of low loss glass and using tight spacing between elements results in an HMIC device with low loss and high isolation through low millimeter wave frequencies.

The protective coating guards against damage to the junction and the anode airbridges during handling and assembly. Ordering Information On the backside of the chip gold metalized pads have been added to produce a solderable surmount device.

V11 Operation of the MASW-002103-1363 PIN Switch Optimal operation of the MASW-002103-1363 is achieved by simultaneous application of negative DC voltage and current to the low loss switching arm and positive DC voltage and current to the remaining switching arm as shown in the circuit diagram below. DC return is achieved via R2 on the RFC path. In the low loss state, the series diode must be forward biased with current and the shunt diode reverse biased with voltage. In the isolated arm, the shunt diode is forward biased with current and the series diode is reverse biased with voltage. Typical Bias Network Example: J1 to J2→ Low Loss R1 = 250 Ω R2 = 450 Ω B2 = -15 V B3 = +6 V Notes: 6. Assume Vf ~ 1 V @ 20 mA 7. R1 = 5 V / 0.02 A = 250 Ω; R2 = 9 V / 0.02 A = 450 Ω 8. PR1 = 0.02 A x 0.02 A x 250 = 0.1 W 9. PR2 = 0.02 A x 0.02 A x 450 = 0.18 W 10. Inductors shown in the above schematic are RF bias chokes. The operating bandwidth of a broad-band PIN diode switch is often dependent on the bias components, particularly the RF bias chokes. It is suggested that the response at the frequencies of interest be measured with all the bias components in place prior to installing of MASW-002103-1363.

The voltage applied to the off arm is allowed to vary provided a constant current is applied through the shunt diode on the off arm. M/A-COM Technology Solutions Inc.

V11 Sample Board Samples test boards are available upon request Handling Procedures Attachment to a circuit board is made simple through the use of standard surface mount technology. Mounting pads are conveniently located on the bottom of the chip and are removed from the active junction locations making it well suited for solder attachment. Connections may be made onto hard or soft substrates via the use of 80Au/20Sn, or RoHS compliant solders. Typical re-flow profiles for provided in Application Note M538 , “Surface Mounting Instructions“ and can viewed in the Customer Support, Technical Resources section of the MACOM website at www.macom.com. For applications where the average power is ≤ 1 W, a thermally conductive silver epoxy may also be used. Cure per manufacturers recommended time and temperature. Typically 1 hour at 150°C. When soldering these devices to a hard substrate, a solder re-flow method is preferred. A vacuum pick up tool with a soft tip is recommended while placing the chip . When soldering to soft substrates, such as Duroid, a soft solder is recommended at the circuit board to chip mounting pad interface to minimize stress due to any TCE mismatches that may exist. Position the die so that its mounting pads are aligned with the circuit board land pads. Solder reflow should not be performed by causing heat to flow through the top surface of the die to the back. Since the HMIC glass is transparent, the edges of the mounting pads can be visually inspected through the die after attachment is completed. 6 M/A-COM Technology Solutions Inc.
