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 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.
