SKY13489-001数据手册RF/IF射频/中频RFID的射频开关规格书PDF

描述 Description

The SKY13489-001 is a single-pole, double-throw (SPDT)LTE/WCDMA/GSM transmit switch. Switching is controlled by anintegrated GPIO interface with a single control pin. Depending onthe logic voltage level applied to the control pin, the antenna portis connected to one of the switched RF outputs (RF1 or RF2)through a low insertion loss path, while the path between theantenna port and the other RF port is in a high isolation state.

No external DC blocking capacitors are required as long as no DCvoltage is applied on any RF path.

The SKY13489-001 is provided in a compact 6-bump,1.135 x 0.735 x 0.400 mm Wafer Level Chip Scale Package(WLCSP) that meets requirements for board-level assembly.Bump diameters are 217 microns with a minimum bump pitch of400 microns.

特性 Features

• Broadband frequency range: 0.7 to 2.7 GHz
• Low insertion loss: 0.3 dB @ 2.7 GHz
• High isolation: 22 dB up to 2.7 GHz
• No external DC blocking capacitors required
• Single GPIO control line with VDD voltage regulator:
• VCTL = 1.35 to 3.00 V
• VDD = 2.45 to 4.80 V
• Small, 6-bump WLCSP, 217 μm diameter, 400 μm pitch (1.135 x 0.735 x 0.400 mm) package (MSL1, 260 °C per JEDEC J-STD-020)

应用 Application

• Smartphones
• Connected Homes
• 4G LTE
