HMC175MS8 / 175MS8E
GaAs MMIC SMT DOUBLE-
BALANCED MIXER, 1.7 - 4.5 GHz
v02.0705
General Description
Features
Functional Diagram
Ultra Small Package: MSOP8
Conversion Loss: 8 dB
LO / IF Isolation: 32 dB
LO / RF Isolation: 30 dB
Input IP3: +18 dBm
Electrical Speci cations, TA = +25° C, LO Drive = +13 dBm
Typical Applications
The HMC175MS8 / HMC175MS8E is ideal for:
• Mini-Base Stations
• Portable Wireless
• PCMCIA
The HMC175MS8 & HMC175MS8E are miniature
double-balanced mixers in 8-lead plastic surface
mount Mini Small Outline Packages (MSOP). The
device can be used as an upconverter or downcon-
verter. The mixer provides exceptional isolation and
Intermodulation performance for applications in high
signal density environments. This device can also
be used as a biphase modulator or demodulator.
The MSOP8 is the smallest footprint available for a
complete double-balanced mixer (0.118” x 0.190” x
0.040”).

[2] Circuit Board Material: Rogers 4350
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 connected
directly to the ground plane similar to that shown. A
sufficient number of via holes should be used to con-
nect the top and bottom ground planes. The evalua-
tion circuit board shown is available from Hittite upon
request.
