The UltraCMOS PE41901 is a SOI based passive double-balanced, Ku band mixer with image rejection. It integrates two mixers, a local oscillator (LO) path 90-degree coupler and RF port baluns on a single die. Integrating these functions provides good image rejection, reduces LO leakage and improves LO to RF isolation. This mixer operates with single-ended signals on the RF and LO ports, and it can be used as an upconversion or downconversion mixer. It supports a broad RF frequency range of 10 to 19 GHz. The intermediate frequency (IF) port accepts broadband quadrature signals from DC to 4 GHz, while the LO port covers a frequency range of 12 to 19 GHz. The PE41901 delivers high LO to RF isolation of 38 dB and LO to IF isolation of 23 dB. It has high linearity of 21 dBm IIP3. The mixer has low conversion loss of 10 dB and achieves image rejection of 25 dB. No external blocking capacitors are required if 0 VDC is present on the LO or RF pins.
The PE41901 image reject mixer is ideal for Ku band earth terminals such as very small aperture terminal (VSAT) block upconverters, point-to-point microwave links and test and measurement (T&M) applications.
