HMC950 v03.0611 Amplifiers - Linear & Power - Chip 3 GaAs pHEMT MMIC 4 WATT POWER AMPLIFIER, 12 - 16 GHz Typical Applications Features The HMC950 is ideal for: Saturated Output Power: +37 dBm @ 23% PAE • Point-to-Point Radios High Output IP3: +44.5 dBm • Point-to-Multi-Point Radios High Gain: 28 dB • VSAT & SATCOM DC Supply: +7V @ 2400 mA • Military & Space No External Matching Required Die Size: 3.23 x 3.45 x 0.1 mm Functional Diagram General Description The HMC950 is a four stage GaAs pHEMT MMIC 4 Watt Power Amplifier which operates between 12 and 16 GHz. The HMC950 provides 28 dB of gain, +37 dBm of saturated output power, and 23% PAE from a +7V power supply. The HMC950 exhibits excellent linearity and is optimized for high capacity point to point and point to multi-point radio systems. It is also ideal for 13.75 to 14.5 GHz Ku Band VSAT transmitters as well as SATCOM applications. The amplifier configuration and high gain make it an excellent candidate for last stage signal amplification before the antenna. All data is taken with the chip in a 50 Ohm test fixture connected via (2) 0.025 mm (1 mil) diameter wire bonds of 0.31 mm (12 mil) length.

Amplifiers - Linear & Power - Chip 3 50 Ohm Microstrip transmission lines on 0.127mm (5 mil) thick alumina thin film substrates are recommended for bringing RF to and from the chip (Figure 1). 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). 0.102mm (0.004”) Thick GaAs MMIC Wire Bond 0.076mm (0.003”) RF Ground Plane Microstrip substrates should be located as close to the die as possible in order to minimize bond wire length. Typical die-to-substrate spacing is 0.076mm to 0.152 mm (3 to 6 mils). 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 > ± 250V ESD strikes. Transients: Suppress instrument and bias supply transients while bias is applied. Use shielded signal and bias cables to minimize inductive pickup. 0.102mm (0.004”) Thick GaAs MMIC Wire 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. 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 may have 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. 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 Ball or wedge bond with 0.025mm (1 mil) diameter pure gold wire. Thermosonic wirebonding with a nominal stage temperature of 150 °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 <0.31mm (12 mils). 3-9 For price, delivery and to place orders: Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or [email protected] HMC950 v03.0611 GaAs pHEMT MMIC 4 WATT POWER AMPLIFIER, 12 - 16 GHz Notes: Amplifiers - Linear & Power - Chip 3 For price, delivery and to place orders: Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or [email protected] 3 - 10
