0.7 to 2.7 GHz SPDT High Power Switch (Single Bit Control) in a WLCSP PackageThe SKY13489-001 is a single-pole, double-throw (SPDT) LTE/WCDMA/GSM transmit switch. Switching is controlled by an integrated GPIO interface with a single control pin. Depending on the logic voltage level applied to the control pin, the antenna port is connected to one of the switched RF outputs (RF1 or RF2) through a low insertion loss path, while the path between the antenna port and the other RF port is in a high isolation state.
No external DC blocking capacitors are required as long as no DC voltage 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 of 400 microns.
- 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)
