SKY13354-368LF Pinout (Top View) Description The SKY13354-368LF is a pHEMT GaAs dual single-pole, doublethrow (SPDT) crossed switch designed for cellular infrastructure band switching applications. The internal crossed switch arrangement is designed to switch balanced RF filters. Switching is controlled by two control voltage inputs (V1 and V2). Depending on the logic voltage level applied to the control pins, the RFCA and RFCB pins are each connected to one of four switched RF outputs (RF1A, RF1B, RF2A, or RF2B) using a low insertion loss path, while maintaining a high isolation path to the alternate port DC blocking capacitors are required on all RF ports. The switch is a “reflective short” on the isolated port. The switch is manufactured in a compact, 2 x 2 mm, 12-pin ex...
