Functional Diagram
General Description
The HMC423MS8 & HMC423MS8E are double balanced mixer ICs with integrated LO amplifiers. This
mixer can operate as an upconverter or downconverter between 0.6 GHz and 1.3 GHz. With the integrated LO amplifier, 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.

LO
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 Amplifier. One external RF bypass
capacitor (10,000 pF) is required.
5
IF
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
necessary IF frequency range. For operation to DC, this pin
must not source/sink more than 18 mA of current or die nonfunction and possible die failure will result.

The circuit board used in the final 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.
