| HMC331 v04.1007 GaAs MMIC PASSIVE FREQUENCY DOUBLER, 12 - 18 GHz INPUT Typical Applications Features Conversion Loss: 14 dB Fo, 3Fo, 4Fo Isolation: 50 dB Passive: No Bias Required Die Size: 0.85 x 0.55 x 0.1 mm 2 FREQUENCY MULTIPLIERS - PASSIVE - CHIP The HMC331 is suitable for: * Wireless Local Loop * LMDS, VSAT, and Point-to-Point Radios * Test Equipment Functional Diagram General Description The HMC331 is a passive miniature frequency doubler MMIC. Suppression of undesired fundamental and higher order harmonics is 50 dB typical with respect to input signal level. The doubler utilizes the same GaAs Schottky diode/balun technology found in Hittite MMIC mixers. It features small size, requires no DC bias, and adds no measurable additive phase noise onto the multiplied signal.

If 0.254mm (10 mil) thick alumina thin film substrates must be used, the die should be raised 0.150mm (6 mils) so that the surface of the die is coplanar with the surface of the substrate. One way to accomplish this is to attach the 0.102mm (4 mil) thick die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly-tab) which is then attached to the ground plane (Figure 2). Microstrip substrate should be brought as close to the die as possible in order to minimize ribbon bond length. Typical die-to-substrate spacing is 0.076mm (3 mils). Gold ribbon of 0.075mm ( 3 mil) width and minimal length <0.31mm ( <12 mils) is recommended to minimize inductance on RF ports., 0.102mm (0.004") Thick GaAs MMIC Wire 3 mil Ribbon Bond 0.076mm (0.003") RF Ground Plane 0.127mm (0.005") Thick Alumina Thin Film Substrate Figure 1. Handling Precautions Follow these precautions to avoid permanent damage. Storage: All bare die are placed in either Waffle or Gel based ESD protective containers, and then sealed in an ESD protective bag for shipment. Once the sealed ESD protective bag has been opened, all die should be stored in a dry nitrogen environment. 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 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. 0.102mm (0.004") Thick GaAs MMIC Ribbon Bond 0.076mm (0.003") RF Ground Plane 0.150mm (0.005") Thick Moly Tab 0.254mm (0.010") Thick Alumina Thin Film Substrate Figure 2. 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. Eutectic Die Attach: A 80/20 gold tin preform is recommended with a work surface temperature of 255 C and a tool temperature of 265 C. When hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be 290 C. DO NOT expose the chip to a temperature greater than 320 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 RF bonds made with 0.003" x 0.0005" ribbon are recommended. These bonds should be thermosonically bonded with a force of 40 - 60 grams. DC bonds of 0.001" (0.025mm) diameter, thermosonically bonded, are recommended. Ball bonds should be made with a force of 40 - 50 grams and wedge bonds at 18 - 22 grams. All bonds should be made with a nominal stage temperature of 150 C. A minimum amount of ultrasonic energy should be applied to achieve reliable bonds. All bonds should be as short as possible, less than 12 mils (0.31 mm). 2 - 30 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC331 v04.1007 GaAs MMIC PASSIVE FREQUENCY DOUBLER, 12 - 18 GHz INPUT Notes 2 FREQUENCY MULTIPLIERS - PASSIVE - CHIP For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com 2 - 31 |
