0.1 to 6.0 GHz DPDT Switch

The SKYA21070 is a pHEMT GaAs double-pole, double-throw (DPDT) switch designed for applications in the broadband frequency range from 0.1 to 6.0 GHz. The switch provides highlinearity performance, low insertion loss, and high isolation in the broadband frequency band.

Switching is controlled by two voltage inputs (V1 and V2). Depending on the logic voltage level applied to the control pins, the ANT1 and ANT2 pins connect to one of two switched RF outputs (RX or TX) through a low insertion loss path while maintaining a high isolation path to the alternate port.

The switch is manufactured in a compact, 1.5 x 1.5 mm, 6-pin exposed pad plastic Micro Leadframe Package Dual (MLPD) package.
