SKYA21029中文资料0.1 to 3.8 GHz SP4T Antenna Switch数据手册Skyworks规格书

描述 Description

The SKYA21029 is a single-pole, four-throw (SP4T) antennaswitch with an internal 50 Ω termination. The high-linearityperformance and low insertion loss achieved by theSKYA21029 make it an ideal choice for embedded cellulartelematics modules and OBD-II cellular modems.

The symmetric port designs provide flexibility in signal routing forboth receive diversity and higher power TD-SCDMA/TDD-LTE,WCDMA/FDD, and LTE transmit/receive applications.

Switching is controlled by three CMOS/TTL-compatible controlvoltage inputs (V1, V2, and V3). Depending on the logic voltagelevel applied to the control pins, the ANT pin is connected to oneof four switched RF outputs (RF1 to RF4) using a low insertionloss path, while the paths between the ANT pin and the other RFpins are in a high isolation state.

The antenna path can also be closed on a 50 Ω load when itneeds to be terminated. The 50 Ω load is internally grounded. Noexternal blocking capacitors are required on the RF paths unlessVDC is externally applied.

The SKYA21029 is manufactured in a compact, 14-pin2.0 x 2.0 mm, Quad Flat No-Lead (QFN) package.
