LINEARITY AND ISOLATION ADVANCED RESISTANCE PASSIVE MIXER MMIC

摘要

Resistive passive frequency that functions as a mixer that down-converts a high-frequency (RF) signal to an intermediate-frequency (IF) signal or up-converts an intermediate-frequency signal to a high-frequency signal using a local oscillation signal. Mixer MMIC is disclosed. The resistive passive frequency mixer MMIC includes a cascode circuit unit 100 including a first FET (FET1) and a second FET (FET2), an isolation circuit unit 200 connected to a rear end of the cascode circuit unit, and the isolation. It includes a high frequency filter 310 and an intermediate frequency filter 320 connected to the rear end of the circuit unit, the isolation circuit unit 200, both ends of the primary side are connected to the cascode circuit unit, one end of the secondary side is the high frequency It is characterized in that it is a spiral transformer connected to the filter 310 and the other end connected to the intermediate frequency filter (320).
