Description
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, sub-
micrometer lithography, trench
isolation, ion implantation, gold
metallization and polyimide inter-
metal dielectric and scratch
protection to achieve excellent
performance, uniformity and
reliability.
