Description
Hewlett-Packard’s IAM-91563 is an
economical 3V GaAs MMIC mixer
used for frequency down-conver-
sion. RF frequency coverage is
from 0.8 to 6 GHz and IF coverage
is from 50 to 700 MHz. Packaged
in the SOT-363 package, this
4.0␣ sq. mm. package requires half
the board space of a SOT-143 and
only 15% the board space of an
SO-8 package.
At 1.9 GHz, the IAM-91563 pro-
vides 9 dB of conversion gain,
thus eliminating an RF or IF gain
stage normally needed with a
lossy mixer. LO drive power is
nominally only -5 dBm, eliminat-
ing an LO buffer amplifier. The
8.5 dB noise figure is low enough
to allow the system to use a low
cost LNA. The -6 dBm Input IP3
provides adequate system linearity
for most commercial applications,
but is adjustable to 0 dBm.
The circuit uses GaAs PHEMT
technology with proven reliability,
and uniformity. The MMIC
consists of a cascode FET struc-
ture that provides unbalanced gm
modulation type mixing. An on-
chip LO buffer amp drives the
mixer while bias circuitry allows a
single +3V supply (through a
choked IF port). The LO port is
internally matched to 50 . The
RF and IF ports are high imped-
ance and require external match-
ing networks.

Notes:
1. Guaranteed specifications are 100% tested in the circuit in Figure 18 in the Applications Information section.
2. Standard deviation number is based on measurement of at least 500 parts from three non-consecutive wafer lots during
the initial characterization of this product, and is intended to be used as an estimate for distribution of the typical
specification.
