Overview
Description
The HFA3101 is an all NPN transistor array configured as a Multiplier Cell. Based on Intersil's bonded wafer UHF-1 SOI process, this array achieves very high fT (10GHz) while maintaining excellent hFE and VBE matching characteristics that have been maximized through careful attention to circuit design and layout, making this product ideal for communication circuits. For use in mixer applications, the cell provides high gain and good cancellation of 2nd order distortion terms.

Is there any lower limit to the frequencies which may be applied to the RF and LO inputs of the HFA3101 mixer?
Question:Is there any lower limit to the frequencies which may be applied to the RF and LO inputs of the HFA3101 mixer? My design will have a lower frequency limit of 12MHz. Answer:You should have no trouble at 12MHz and above. There is no internal ac coupling that ...
