Patent ID: 8249541

Claim:
A sub-harmonically pumped conversion mixer arrangement comprising: a transistor arrangement and transistor terminals for application of a local oscillator (LO) signal and receiving and extracting a radio frequency (RF) signal and for receiving and extracting a mixed intermediate frequency (IF) signal, the transistor arrangement further comprising: at least one NMOS transistor and at least one PMOS transistor, the drain of said at least one NMOS transistor being interconnected with the drain of said at least one PMOS transistor and the gate of said at least one PMOS transistor being interconnected with the gate of said at least one NMOS transistor, wherein the source of the PMOS transistor is interconnected with the source of the NMOS transistor; and wherein the transistor arrangement comprises three separate transistor terminals, a gate terminal, a source terminal and a drain terminal, the terminals being adapted to provide a separate port for each of the LO, RF and IF signals respectively.
