IAM-91563
0.8–6 GHz 3V Downconverter
Data Sheet
Description
Avago’s IAM-9563 is an economical 3V GaAs MMIC mixer
used for frequency down-conversion. RF frequency cover-
age 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-43 and
only 5% the board space of an SO-8 package.
At .9 GHz, the IAM-9563 provides 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, eliminating 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 IP
3
provides adequate
system linearity for most commercial applications, but is
adjustable to 0 dBm.
The circuit uses GaAs PHEMT technology with proven reli-
ability, and uniformity. The MMIC consists of a cascode FET
structure 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 Ω. The
RF and IF ports are high impedance and require external
matching networks.

Notes:
. Guaranteed specifications are 00% tested in the circuit in Figure 8 in the Applications Information section.
. 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.
