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.
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.
