| v02.1201 MICROWAVE CORPORATION HMC132 GaAs MMIC HIGH-ISOLATION SPDT SWITCH, DC - 15 GHz Features Bandwidth: DC - 15 GHz High Isolation: >40 dB Non-Reflective Design Typical Applications The HMC132 is ideal for: * Wireless Local Loop * MMDS & Wireless LAN * UNII & HiperLAN * Fiber Optics Functional Diagram General Description The HMC132 chip is a fast, broadband SPDT switch featuring high (40 dB) isolation over the entire band, provided by on-chip ground vias. The switch is non-reflective at both the RF1 and RF2 ports. A negative control voltage of 0 / -5 Vdc to 0 / -7 Vdc controls the channel selection. Redundant A/B control lines lend versatility to MIC layouts. 7 SWITCHES - CHIP Electrical Specifications, TA = +25 C, With 0/-5V control, 50 Ohm System Parameter Inser tion Loss Frequency DC - 6 GHz DC - 15 GHz DC - 6 GHz DC - 15 GHz DC - 6 GHz DC - 15 GHz 0.5 - 15 GHz 0.5 - 15 GHz 0.5 - 15 GHz 45 37 14 9.5 +20 +22 +38 Min.

Cleanliness: Handle the chips in a clean environment. DO NOT attempt to clean the chip using liquid cleaning systems. Static Sensitivity: Follow ESD precautions to protect against > 250V ESD strikes. Transients: Suppress instrument and bias supply transients while bias is applied. Use shielded signal and bias cables to minimize inductive pick-up. General Handling: Handle the chip along the edges with a vacuum collet or with a sharp pair of bent tweezers. The surface of the chip has fragile air bridges and should not be touched with vacuum collet, tweezers, or fingers. Mounting The chip is back-metallized and can be die mounted with AuSn eutectic preforms or with electrically conductive epoxy. The mounting surface should be clean and flat. 7 SWITCHES - CHIP Eutectic Die Attach: A 80/20 gold tin preform is recommended with a work surface temperature of 255 deg. C and a tool temperature of 265 deg. C. When hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be 290 deg. C. DO NOT expose the chip to a temperature greater than 320 deg. C for more than 20 seconds. No more than 3 seconds of scrubbing should be required for attachment. Epoxy Die Attach: Apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fillet is observed around the perimeter of the chip once it is placed into position. Cure epoxy per the manufacturer's schedule. Wire Bonding Ball or wedge bond with 0.025 mm (1 mil) diameter pure gold wire (DC Bias) or ribbon bond (RF ports) 0.076 mm x 0.013 mm (3 mil x 0.5 mil) size is recommended. Thermosonic wirebonding with a nominal stage temperature of 150 deg. C and a ball bonding force of 40 to 50 grams or wedge bonding force of 18 to 22 grams is recommended. Use the minimum level of ultrasonic energy to achieve reliable wirebonds. Wirebonds should be started on the chip and terminated on the package or substrate. All bonds should be as short as possible <0.31 mm (12 mils). 7-6 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Visit us at www.hittite.com, or Email at sales@hittite.com v02.1201 MICROWAVE CORPORATION HMC132 GaAs MMIC HIGH-ISOLATION SPDT SWITCH, DC - 15 GHz Notes: 7 SWITCHES - CHIP For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Visit us at www.hittite.com, or Email at sales@hittite.com 7-7 |
