Typical Applications
The HMC423MS8 is ideal for:
Base Stations
Portable Wireless
CATV/DBS
ISM
* Unless otherwise noted, all measurements performed as downconverter, IF= 100 MHz.
The HMC423MS8 is a double balanced mixer
IC with an integrated LO amplifi er. This mixer
can operate as an upconverter or downconverter
between 0.6 GHz and 1.3 GHz. With the inte-
grated LO amplifi er, the mixer requires an LO
drive level of only 0 dBm, and requires only 15mA
from a single positive +3V rail. The mixer has 8
dB of conversion loss, an input P1dB of +8 dBm
and an input third order intercept point of +15
dBm at 1.3 GHz.

Description
Interface Schematic
1
LO Port
This pin is AC coupled and matched to 50 Ohm from
0.6 - 1.3 GHz.
2, 3, 6, 7
GND
Pins must connect to RF ground.
4
Vdd
Power supply for the LO Amplifi er. One 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 whose value has been chosen to pass the neces-
sary IF frequency range. For operation to DC, this pin must not
source/sink more than 18 mA of current or die non-function and
possible die failure will result.

Evaluation PCB
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 should be connected directly to the ground
plane similar to that shown. A suffi cient 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.
