| 2 - 6 GHz Cascadable GaAs MMIC Amplifier Technical Data MGA-64135 Features * Cascadable 50 Gain Block * Broadband Performance: 2-6 GHz 12.0 dB Typical Gain 0.8 dB Gain Flatness 12.0 dBm P1 dB * Single Supply Bias * Cost Effective Ceramic Microstrip Package applications include narrow and broadband IF and RF amplifiers for commercial, industrial, and military requirements. This MMIC is a cascade of two stages, each utilizing shunt feedback to establish a broadband impedance match. The source of each stage is AC grounded to allow biasing from a single positive power supply. The interstage blocking capacitor as well as a resistive "self-bias" network are included on chip. The die is fabricated using HP's nominal .5 micron recessed Schottky-barrier-gate, gold metallization and silicon nitride passivation to achieve excellent performance, uniformity, and reliability. 35 Micro-X Package Description The MGA-64135 is a high performance gallium arsenide Monolithic Microwave Integrated Circuit (MMIC) housed in a cost effective, microstrip package. This device is designed for use as a general purpose 50 ohm gain block in the 2 to 6 GHz frequency range. Typical Typical Biasing Configuration Vd RFC 4 3 IN 1 MGA C block OUT 2 5965-9005E 6-192 MGA-64135 Absolute Maximum Ratings Symbol Vd Pdiss Pin Tch TSTG Parameter Device Voltage Total Power Dissipation[2] CW RF Input Power Channel Temperature Storage Temperature[3] Units V mW dBm C C Absolute Maximum[1] 12 650 +13 175 -65 to 175 Thermal Resistance: Liquid Crystal Measurement: jc = 150C/W [4]; TCH = 150C 1 m Spot Size [5] Notes: 1. Operation of this device above any one of these parameters may cause permanent damage. 2. Derate linearly at 8.3 mW/C for TCASE > 103C. 3. Storage above +150C may tarnish the leads of this package making it difficult to solder into a circuit. After a device has been soldered into a circuit, it may be safely stored up to 175C. 4. The thermal resistance value is based on measurements taken with the device soldered to a 25 mil Teflon PCB. 5. The small spot size of this technique results in a higher, though more accurate determination of jc than do alternate methods. See MEASUREMENTS section for more information.
