Features, Applications


The is a balanced Schottky diode mixer based on a six quarter wave ring structure. This circuit is manufactured with the BES-MMIC process: 1 �m Schottky diode device, air bridges, via holes through the substrate, stepper lithography. It is available in chip form.

W-band LO and RF frequency range Low conversion loss IF from to 100MHz High LO/RF isolation High LO/AM noise rejection Very low IF noise Low LO input power Small chip size: 0.10 mm

Typical conversion characteristic LO power ; IF=10MHz (measurement in test fixture)
LO,RF frequency range IF frequency range Conversion loss LO/RF isolation IF noise density @ 100kHz
ESD Protection : Electrostatic discharge sensitive device. Observe handling precautions !

Tamb. = 25�C, used according to section "Typical bias and IF configuration" and "Typical assembly and RF configuration" Symbol
