The IVA-14 series MMlCs are variable gain amplifiers. The IVA-14208 is housed in a miniature low cost plastic surface mount package. The IVA-14228 is housed in a miniature hermetic ceramic surface mount package. Both devices can be used in any combination of single-ended 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 or limiting for fiber optic systems (e.g. SONET) with data rates up to 3.4 Gbits/s, mobile radio and satellite receivers, millimeter wave receiver IF amplifiers and communications receivers.
The IVA series of variable gain amplifiers is fabricated using Hewlett-Packard's 10 GHz fT, 25 GHz f MAX ISOSAT™-1 silicon bipolar process. This process uses nitride self-alignment, submicrometer lithography, trench isolation, ion implantation, gold metallization and polyimide intermetal dielectric and scratch protection to achieve excellent performance, uniformity and reliability.
