Abstract :
High-order, bidirectional, DC-20-GHz switch networks are discussed. Single-chip 1×2, 1×4, and 2×2 switch MMICs have been demonstrated. Multiple chips have been used to demonstrate 4×4 and 1×16 switches. The switches all use a combination of series and shunt passive FET switching elements. The 1×4 switch is made of a single stage of switching elements, rather than the usual two stages of 1×2 switches. The 2×2 switch is comprised of two stages of 1×2 switches. The multiple-chip 4×4 switch is made of four stages of 1×2 switches (using the 2×2 switch MMICs). Two stages of 1×4 switches are used to make the 1×16 switch
