HMC423MS8 / 423MS8E
v02.0705
General Description
Features
Functional Diagram
Electrical Speci cations, TA = +25° C
Typical Applications
The HMC423MS8 / HMC423MS8E is ideal for:
• Base Stations
• Portable Wireless
• CATV/DBS
• ISM
The HMC423MS8 & HMC423MS8E are double bal-
anced mixer ICs with integrated LO ampli ers. This
mixer can operate as an upconverter or downcon-
verter between 0.6 GHz and 1.3 GHz. With the inte-
grated LO ampli 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 conver-
sion loss, an input P1dB of +8 dBm and an input third
order intercept point of +15 dBm at 1.3 GHz.

Pin Number Function Description Interface Schematic
1LO
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.
4Vdd
Power supply for the LO Ampli er. One external RF bypass
capacitor (10,000 pF) is required.
5IF
This pin is DC coupled. For applications not requiring opera-
tion to DC, this port should be DC blocked externally using a
series capacitor whose value has been chosen to pass the
necessary 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.
8RF
This pin is DC coupled and matched to 50 Ohm from
0.6 - 1.3 GHz

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 should be connected 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.
