Description
The IAM-81008 is a complete low
power consumption, double
balanced active mixer housed in a
miniature low cost plastic surface
mount package. It is designed for
narrow or wide bandwidth commer-
cial and industrial applications
having RF inputs up to 5 GHz.
Operation at RF and LO frequencies
less than 50 MHz can be achieved
using optional external capacitors
to ground. The IAM-81008 is
particularly well suited for applica-
tions that require load-insensitive
conversion and good spurious
signal suppression with minimum
LO and bias power consumption.
