HMC488MS8G / 488MS8GE
v03.0608
General Description
Features
Functional Diagram
Low Conversion Loss: 7 dB
Double-Balanced Topology
Integrated LO Ampli er: 0 to +6 dBm Drive
Input IP3: +15 dBm
Single Supply: +5V @ 46 mA
MSOP8-G Package: 14.8 mm2
Electrical Speci cations, TA = +25° C, IF= 100 MHz, Vdd= 5V
Typical Applications
The HMC488MS8G / HMC488MS8GE is ideal for:
• Basestations & Repeaters
• Access Points & Subscribers
• UNII, ISM, WLAN & WiMAX
• Point to Point/Multi-Point Radios
• VSAT Radio
The HMC488MS8G(E) is an ultra miniature double-
balanced mixer with integrated LO ampli er in an 8
lead plastic SMT MSOP8-G 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 ampli er 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.

Pin Number Function Description Interface Schematic
1LO This pin is AC coupled
and matched to 50 Ohms.
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.
5IF
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.
8RF This pin is DC coupled
and matched to 50 Ohms.

Evaluation PCB
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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.
