The IVA-05228 is a variable gain amplifier housed in a miniature ceramic hermetic surface mount package. This device can be used in any combination of singleended or differential inputs or outputs (see Functional Block Diagram). The lowest frequency of operation is limited only by the values of user selected blocking and bypass capacitors.
Typical applications include variable gain amplification for fiber optic systems (e.g., SONET) with data rates up to 2.0 Gb/s, mobile radio and satellite receivers, millimeter wave receiver IF amplifiers and communication receivers.
The IVA series of variable gain amplifiers is fabricated using HP's 10 GHz fT, 25 GHz fMAX ISOSAT™-I silicon bipolar process. This process uses nitride self-alignment, submicrometer lithography, trench isolation, ion implantation, gold metallization and polyimide inter-metal dielectric and scratch protection to achieve excellent performance, uniformity and reliability.
