Silicon Bipolar MMIC 1.5 GHz Variable Gain Amplifier Technical Data IVA-05128 Features • 50 MHz to 1.5 GHz 28 Package Bandwidth • Data Rates up to 2.0 Gbit/s • High Gain: 26 dB Typical • Wide Gain Control Range: 30␣ dB Typical • Differential Output Capability • Bias VCC - Vee = 5 V • 5 V TTL Compatible Vgc Control Voltage, lgc < 3 mA • Hermetic Ceramic Surface Mount Package Description PIN 1 The IVA-05128 is a variable gain amplifier housed in a miniature ceramic hermetic surface mount package. It is designed for narrow or wide bandwidth commercial, industrial and military applications that require high gain and wide gain control range. The amplifier can be used in a singleended or differential output configuration. For low frequency applications (<50 MHz) a bypass capacitor and series resistor are connected to pin 4, the AC Input Ground lead. Typical applications include variable gain amplification for fiberoptic systems at data rates in excess of the 1.24 Gb/s SONET standard, mobile radio and satellite receivers, millimeter wave receiver IF amplifiers and communications receivers. Typical Biasing Configuration and Functional␣ Block␣ Diagram The IVA series of variable gain amplifiers is fabricated using HP’s 10 GHz fT, 25 GHz fMAX ISOSATTM-I silicon bipolar process. This process uses nitride selfalignment, submicrometer lithography, trench isolation, ion implantation, gold metallization and polyimide inter-metal dielectric and scratch protection to achieve excellent performance, uniformity and reliability. 6-173 5965-9974E Absolute Maximum Ratings Thermal Resistance:[2,4] θjc = 50°C/W Absolute Maximum[1] Parameter Device Voltage 8V Power Dissipation[2,3] 600 mW Input Power +14 dBm Vgc - Vee 7V Junction Temperature 200°C Storage Temperature -65°C to 200°C Notes: 1.
