Description
The IAM-82028 is a complete
moderate-power double-balanced
active mixer housed in a
miniature ceramic hermetic
surface mount package. It is
designed for narrow or wide
bandwidth commercial, industrial
and military applications having
RF inputs up to 5 GHz and IF
outputs from DC to 2 GHz.
Operation at RF and LO
frequencies less than 50 MHz can
be achieved using optional
external capacitors to ground.
The IAM-82028 is particularly well
suited for applications that
require load-insensitive
conversion gain and good
spurious signal suppression and
moderate dynamic range with
minimum LO power. Typical
applications include frequency

downconversion, modulation,
demodulation and phase
detection for fiber-optic, GPS
satellite navigation, mobile radio,
and communications receivers.
The IAM series of Gilbert
multiplier-based frequency
converters is fabricated using
HP’s 10 GHz fT, 25 GHz f
ISOSATTM-I silicon bipolar process
which 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.
