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 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.
SO-8 Package
The IVA series of variable gain
amplifiers is fabricated using HP’s
10 GHz fT, 25 GHz f
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.

Notes:
1. The recommended operating voltage range for this device is 4 to 6 V. Typical performance as a function of voltage is on the following
page.
2. As measured using Input Pin 1 and Output Pin 6, with Output Pin 7 terminated into 50 ohms and Input Pin 4 at AC ground.
3. Referenced from 50 MHz Gain.
4. The recommended gain control range for these devices for dynamic control is 0 to 4.2 V. Operation at gain control settings above 4.2V
may result in gain increase rather than gain decrease.
