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.

Notes:

1. The recommended operating voltage range for these devices is 5 to 8 V. Typical performance as a function of voltage is shown in the

graphs on the following pages.

2. The recommended gain control range for these devices for dynamic control is 0 to 4.2 V. Operation at gain control settings above 4.2 V

may result in gain control increase rather than gain decrease. See figures 4 and 19.
