General Description
Features
Functional Diagram
Conversion Loss: 7 dB
Integrated LO Amplifi er: 0 to +6 dBm Drive
Input IP3: +15 dBm
Single Positive Supply: 5V @ 46 mA
Electrical Specifi cations,
T
A
= +25 C, IF= 100 MHz, Vdd= 5V
Typical Applications
The HMC488MS8G is ideal for:
UNII, ISM & WLAN
Point to Point/Multi-Point Radios
VSAT
The HMC488MS8G is an ultra miniature double-
balanced mixer with an integrated LO amplifi er
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 amplifi 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.

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.
