FET MIXER, 1.1 - 1.7 GHz
v02.1201
General Description
Features
Functional Diagram
IP3 (Input): +24 dBm @ +11 dBm LO
LO Range = +3 to +11 dBm
Conversion Loss: 7 dB
LO/RF Isolation: 40 dB
Electrical Specifi cations,
T
A
= +25 C, As a Function of LO Drive, Vgg = -1.5 Vdc
Typical Applications
*Unless otherwise noted, all measurements performed as downconverter, IF= 70 MHz.
The HMC296MS8 is a low LO drive, high IP3 dou-
ble-balanced FET mixer in an 8 lead plastic surface
mount MSOP package. This MMIC mixer is con-
structed of switched GaAs FETs and novel planar
transformer baluns on the chip. The device can be
used as an up or downconverter for 1.1 to 1.7 GHz
applications. The consistent MMIC performance will
improve system operation. The package dimensions
are 0.118" x 0.192" (3.0mm x 4.9mm).
The HMC296MS8 is ideal for:
Miniature Basestations
PCMCIA
Portable Wireless
WirelessLAN

The circuit board used in the fi 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
suffi cient 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.
