SKYA21038数据手册RF/IF射频/中频RFID的射频开关规格书PDF

描述 Description

The SKYA21038 is a single-pole, double-throw (SPDT) switchintended for mode switching in WLAN applications. Usingadvanced switching technologies, the SKYA21038 maintains lowinsertion loss and high isolation for all switching paths.

The high-linearity performance and low insertion loss achieved bythe switch make it an ideal choice for low-power transmit/receiveapplications. Depending on the logic voltage applied to the controlpin (VCTL), the INPUT pin is connected to one of the two switchedRF outputs (OUTPUT1 or OUTPUT2) using a low insertion losspath, while the path between the INPUT pin and the other OUTPUTpin is in a high-isolation state. The switch is \"reflective short\" onthe isolated port.

The SKYA21038 has integrated DC blocking capacitors, so noexternal 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)package.
