Description
The IVA-05208 is a variable gain
amplifier housed in a miniature
low cost plastic surface mount
package. This device 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 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.
SO-8 Package
PIN 1
The IVA series of variable gain
amplifiers is fabricated using HP’s
10 GHz f_T, 25 GHz f_MAX
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.

Good grounding of Pins 2, 3 is critical for proper
operation and good VSWR performance of this part.
* Optional: For Single-Ended Output operation, Pin 7
may be left unterminated (no C_block or 50 Ω)
