Description
The IAM-81028 is a complete low-
power-consumption 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 1 GHz.
Operation at RF and LO
frequencies less than 50 MHz can
be achieved using optional
external capacitors to ground.
The IAM-81028 is particularly well
suited for applications that
require load-insensitive conver-
sion gain and good spurious signal
suppression with minimum LO
and bias power consumption.
Typical applications include
frequency down conversion,

modulation, demodulation and
phase detection for fiber-optic,
GPS satellite navigation, mobile
radio, and battery powered
communications receivers.
