The introduction by Padin et al. in 1996 of an SIS mixer with an integrated IF amplifier eliminates the need for an IF isolator and makes possible SIS receivers with multi-octave IF's. To realize a wide IF bandwidth, an SIS mixer must be designed with low IF capacitance and inductance. This paper describes an SIS mixer in which the RF circuit is effectively decoupled from the IF circuit, and a compact high-impedance RF choke circuit is used, resulting in low output capacitance and inductance.
