Single Positive Supply: 5V @ 46 mA
Functional Diagram
General Description
The HMC488MS8G is an ultra miniature doublebalanced mixer with an integrated LO amplifier
in an 8 lead plastic SMT MSOP covering 4 - 7
GHz. This passive MMIC mixer integrates a GaAs
Schottky diode quad, transformer baluns and a LO
buffer on a single chip yielding a low conversion
loss of 7 dB coupled with an input IP3 of +15 dBm.
The LO buffer amplifier can be driven from 0 to +6
dBm and requires a single supply of +5V @ 46
mA. The device can be used as an upconverter,
downconverter or bi-phase (de)modulator for a
variety of point-to-point/multipoint, VSAT, telemetry
or broadband WLAN applications.

Description
1
LO
This pin is AC coupled & matched to 50 Ohm
from 4.0 to 7.0 GHz.
2, 6, 7
GND
This pin must be connected to RF ground.
3, 4
Vdd
These pins are power supply for LO amp.
An external RF bypass capacitor (10,000 pF) is required.
5
IF Port
This pin is DC coupled. For applications not requiring
operation to DC this port should be DC blocked externally
using a series capacitor. Choose value of capacitor to pass
IF frequency desired. For operation to DC, this pin must not
sink/source more than 40 mA of current or failure may result.
8
RF Port
This pin is DC coupled & matched to 50 Ohm
from 4.0 to 7.0 GHz

The circuit board used in the final application should
use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground
leads and exposed paddle should be connected directly
to the ground plane similar to that shown. A sufficient
number of VIA holes should be used to connect the top
and bottom ground planes. The evaluation circuit board
shown is available from Hittite upon request.
