A high linearity InGaP/GaAs HBT up-conversion double balanced mixer with common base drive stage

A high linearity double balanced mixer has been developed using InGaP/GaAs HBT technology. Features of the design include a common base drive stage and a common collector output buffer amplifier. The up-conversion mixer shows an input-referred 1-dB compression point (P/sub 1dB, IN/) of 15 dBm and a...

Description
Summary:A high linearity double balanced mixer has been developed using InGaP/GaAs HBT technology. Features of the design include a common base drive stage and a common collector output buffer amplifier. The up-conversion mixer shows an input-referred 1-dB compression point (P/sub 1dB, IN/) of 15 dBm and a third order input intercept point (IIP3) of 21.6 dBm. The chip size of the developed mixer is 1.17 mm /spl times/ 1 mm. The isolation of LO-RF and LO-IF in the up-conversion mixer shows 58.5 dB and 86.2 dB, respectively.
