Functional Diagram
General Description
The HMC423MS8 & HMC423MS8E are double bal-
anced mixer ICs with integrated LO amplifiers. This
mixer can operate as an upconverter or downcon-
verter between 0.6 GHz and 1.3 GHz. With the inte-
grated 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 conver-
sion loss, an input P1dB of +8 dBm and an input third
order intercept point of +15 dBm at 1.3 GHz.

Power supply for the LO Amplifier. One external RF bypass

IF
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.
