The SKYA21038 is a single-pole, double-throw (SPDT) switch
intended for mode switching in WLAN applications. Using
advanced switching technologies, the SKYA21038 maintains low
insertion loss and high isolation for all switching paths.
The high-linearity performance and low insertion loss achieved by
the switch make it an ideal choice for low-power transmit/receive
applications. Depending on the logic voltage applied to the control
pin (VCTL), the INPUT pin is connected to one of the two switched
RF outputs (OUTPUT1 or OUTPUT2) using a low insertion loss
path, while the path between the INPUT pin and the other OUTPUT
pin is in a high-isolation state. The switch is "reflective short" on
the isolated port.
The SKYA21038 has integrated DC blocking capacitors, so no
external DC blocking capacitors are required.
The switch is manufactured in a compact, 1 × 1 × 0.5 mm,
6-pin exposed pad plastic Micro Leadframe Package Dual (MLPD)
