 SP4T switch

Hittite recently unveiled the HMC1084LC4, a reflective GaAs MESFET single pole four throw (SP4T) switch that is aimed at applications that need broadband performance, low insertion loss, fast switching speed and high-power handling.

The HMC1084LC4 switch features frequency coverage from 23 to 30GHz and it is controlled with 0/-3V logic. It also boasts a switching speed for 15ns (rise and fall times) and consumes less DC current than PIN diode solutions. The device also exhibits 11dB return loss, 26dB isolation, 2.8dB insertion loss and handles high power excess of 27dBm.

The switch is housed in a compact leadless 4x4 mm ceramic SMT package that is compatible with SMT. The datasheet for the HMC1084LC4 can be found here.
